Dragon Codex
From Dragon Mania Legends (DML) Wiki
The Dragon Codex 
is a major story and gameplay element in Dragon Mania Legends that is unlocked after breeding, hatching and housing the very first Smoke Dragon. After being unlocked, the Codex can be found and accessed by tapping the 
button in the upper-right corner of the screen when viewing the Archipelago. The main feature of the Dragon Codex is to give up-to-date information on Dragons. There are three aspects to the Dragon Codex, namely the Codex, the Collections, and the Codex Entries.
The Dragon Codex provides the ability to purchase additional Dragon eggs at any time for any Dragon that a Trainer currently has on their islands, including any Limited-Time Dragon previously obtained, as long as these Dragons can be purchased in exchange for Gold or Gems. Boss Dragons and regular Dragons that can be bred normally or within a limited-time period, along with the active VIP Dragons, can always be purchased, regardless if the Trainer has them on their islands or not. Boss Dragons can only be purchased once, unless exceptions occur, and only if they have been unlocked through defeating them in Normal Mode.
After opening the Dragon Codex, the Trainer has two tabs and one button. The File:Collections Tab.png and File:Dragon Codex Tab.png tabs are used to toggle between the Collections and the Codex, respectively while the File:Leaderboard Button.png button is used to access the Dragon Collector Leaderboard.
Codex
The Codex is a major feature that has an overall count of Dragons that can be obtained and Dragons that have been obtained along with an individual count showing for multiples of obtained Dragons. There is an image slot for every Dragon in the game (excluding Chronos and Clan Dragons). Images will show in color for all Dragons that have been obtained (including any Limited-Time Dragon), containing their mugshot, Elements and name. Grayed-out images will appear for Dragons that are available, but not yet obtained. An image of a lock 
is present on slots of Dragons that must first be unlocked before they can be obtained.
Though slots are shown for each Limited-Time Dragon in the Codex, no image is shown and their basic information (Level 1 Codex Entries) can only be viewed while they are available in the game, such as when they are Dragon of the Week or Dragon of the Month, or part of a currently-ongoing event. Basic information for all other Dragons can be viewed by selecting their image. Additionally, the Codex will display the total count of unique Dragons the Trainer currently has separated with a slash by the total count of unique Dragons in the game. Neither count includes Chronos and the Clan Dragons.
The Dragons can be filtered through the 
option. From here, the Trainer can filter them by:
- a specific Dragon using the
- a specific Element (which shows any Dragon with that Element)
Boss Dragons- all Dragons
- Limited-Time Dragons
- Arena Dragons
- Card Dragons
VIP Dragons- Enchantment Dragons
- Dungeon Dragons
- Card Dragons obtained from Clan Events
- Reward Dragons
The filtered view can also be sorted by "rarity", which will sort them by classification/type or by "unlock". When selecting the order by "unlock", all Dragons are sorted according to their highest Element where Limited-Time Dragons are shown first, followed by the others.
In addition to the above filtering options, the Trainer can also check the Show owned only box to have the Codex display only those Dragons that are currently under the ownership of the Trainer.
The Trainer can also compare 
their collection of obtained Dragons to that of other Trainers by first visiting their islands and then selecting the 
button at the bottom right of the page.
Whenever a new Dragon is hatched for the very first time and placed in a Habitat, the Codex will appear and it will fill in its snapshot. If the Dragon has an entry in a collection, the Collections menu will appear instead. If the last housed species of a Trainer's Dragon is sold, its snapshot in the Codex will become grayed-out again, but the same will not happen in the Collections if the Dragon has an entry there.
Collections
The collections are made up of different groups of Dragons that are collected for rewards consisting of Gems (ranging from 5 to 35). These collections are grouped into categories such as early-game Dragons, all Common/Uncommon Normally-Breedable Dragons of an Element, Dragons required to breed Legendaries, Dungeon-Exclusive Dragon, VIP-Exclusive Dragon, and so on and so forth. The collections are listed in their complete form and can be hidden through the File:Hide Collection Button.png button and unhidden through the File:Unhide Collection Button.png button.
Codex Entries
A Dragon's Codex Entry can be viewed from multiple places in the game, including, but not limited to, the Main Shop, inventory, current ongoing events, by pressing the File:Information Button.png button when visiting the Dragon in their Habitat, or selecting their image in the Codex. Depending from where it is accessed, the Codex Entry will show different information. Codex Entries for Boss Dragons can only be accessed through the Codex (at all times) or the Main Shop (only if it has been previously beaten in Normal Mode). A Codex Entry accessed from a Habitat is unique for the selected Dragon as it displays that Dragon's own features. Codex Entries accessed from anywhere else only display the base features of that particular species of Dragons.
Base Codex Entry
When viewing a Dragon's Codex Entry through any method other than from Habitats, the Trainer will see the species name and given name, Elements and rarity of the Dragon, its Level 1 (base) stats and Dragon Collector Points (neither is shown for Boss Dragons), the four (grayed out) Enchantment Stars if the Dragon can be enchanted and the (grayed out) skills that can be taught to the Dragon in the Dragon Academy, a text showing whether the Trainer already has the Dragon or not on their islands, and some flavorful text that explains the interaction between the Dragon and its trainer, other Dragons, the opposing characters, or/and other gameplay features. Additionally, in the bottom-left corner of the Dragon's image, the _Button.png){kind=small}
button can be pressed to display the egg of that Dragon and the _Button.png){kind=small}
button to switch back to the current form.
In the case of Legendary and Divine Dragons, whenever they have any secondary Elements awoken, this Codex Entry changes to reflect the new Element as well as the base stats affected by that Element.
If the Trainer has the Dragon housed or stored on their islands, the File:Go Now! Button.png option is made available and pressing it will take the Trainer directly to that Dragon in its Habitat or to the Dragon Vault, respectively. If the Trainer has more than one species of that Dragon, pressing the button will bring up a menu with all the Dragons of that species, giving the Trainer the option to choose the desired duplicate.
Under the image of the Dragon, depending on its obtaining method, a button might be made available for various purposes:
- As explained in the beginning of this article, in the case of most owned Dragons, the Trainer might be given the option to purchase additional egg duplicates through a green button indicating the cost and currency of the Dragon. The button will always be shown for Normally-Breedable Dragons, the current Dragon of the Week and Dragon of the Month, Dragons for which a Breeding Token is currently active, and Boss Dragons which the Trainer does not posses, but has unlocked through battling (with very rare exceptions, the Trainer can have only one of each Boss Dragon, thus duplicates can not be purchased for them).
- The File:Breed This Button.png is shown for Normally-Breedable Dragons that the Trainer has not yet obtained and pressing the button will take the Trainer to the Breeding Den and will automatically select two possible parent Dragons.
- The File:Hatch Button 2.png button will always be shown for Card-Segment Dragons for which the Trainer has sufficient Dragon Pieces to hatch, regardless if the Trainer already has the Dragon or not, and for other Dragons that are in the Trainer's
inventory, and pressing it will send that Dragon to be hatched, provided there are free nests in the Hatchery. - The File:Get Pieces Button.png button is shown for Card Dragons the Trainer does not have on their islands and whose Pieces can be obtained from card packs, and pressing it will take the Trainer to the section of the Main Shop where card packs can be purchased.
- The File:Find Pieces Button.png button is shown for limited Card Dragons that are obtained from events other than Clan Events, and pressing it will take the Trainer to that event. The button is only shown if the event is currently ongoing.
- The File:Clan Button (Codex Entry).png button is shown for limited Card Dragons that are obtained solely from Clan Events, and pressing it will take the Trainer to the current active Clan Dragon.
- In the case of Enchantment Dragons, the File:Enchanted Breeding Button (Codex Entry).png button is always shown for Dragons that are obtained via Enchanted Breeding, and pressing it will take the Trainer to the aforementioned screen (if the Breeding Den is free), while the File:Visit League Button (Codex Entry).png button is shown for Dragons that are obtained from the Enchantment League and the Trainer does not yet have, and pressing it will bring up the Enchantment menu. In case the Trainer has not yet unlocked the Enchantment feature, the following text will be shown instead of a button: You will need your 3 strongest dragons to be Level 16 or higher, waiting in their habitats and ready for action to unlock ENCHANTMENT!
- The File:View Bundle Button.png button is shown if the Dragon is not owned by the Trainer, does not appear in the Dragons section of the Main Shop, and can currently be purchased through a promotion. Pressing this button will bring up the promotion the Dragon is part of.
- In the case of VIP-Exclusive Dragons, the File:Become A VIP Button (Codex Entry).png button is shown if the Trainer has the necessary VIP Level to breed or purchase that Dragon, but their VIP membership is inactive, while the File:Reach VIP level Button (Codex Entry).png button is shown if the Trainer must become a certain VIP level, which will be indicated on the button, before being able to breed or purchase that Dragon. Pressing either button will bring up the VIP interface.
- For Dragons that are currently the prize for an ongoing event, the File:Visit Event Button (Codex Entry).png button will be shown and pressing it will take the Trainer to that event.
- Dragons that are obtained via the Dragon League will have the File:Arena Button (Codex Entry).png button shown, and pressing it will open the league menu, while Dragons that are obtained from the Clockwork Dungeon will have the File:Clockwork Dungeon Button (Codex).png button shown, and pressing it will take the Trainer to the Clockwork Dungeon. However, if the Trainer has not yet reached Level 16, the level necessary to unlock the Dungeon, the File:Campaign Map Button (Codex Entry).png button will be shown instead accompanied by the following text: Reach Level 16 to unlock Otto's Dungeon. Inside the dungeon, fight against waves of enemies and collect Dungeon Tokens to get unique dragons and other rare items!
- In the case of some Reward-Exclusive Dragons: the File:Totem Of Friendship Button (Codex Entry).png button will be shown for Dragons that are obtained from the Totem of Friendship, and pressing it will open the menu of that building; the File:Recruitment Code Button (Codex Entry).png button will be shown for Dragons obtained from recruiting Trainers, and pressing it will take the Trainer to the screen showing their recruitment code; the File:Connect Button 2.png button will be shown for Dragons obtained via connecting to Facebook, and pressing it will bring up the window for this purpose. No button is shown for Dragons obtained through the Daily Prizes, only the following text: Day x Login Bonus, where x stands for the day in which that Dragon is given.
- The File:Campaign Map Button (Codex Entry).png button is displayed for Dragons that are obtained from defeating certain quests in Normal Mode and Heroic Mode, and pressing it will take the Trainer to that mode. The button is also displayed for Boss Dragons that have not yet been defeated in Normal Mode, and pressing it will take the Trainer to that mode.

- The File:Visit Shop Button (Codex Entry).png button was available during the time Midgarden was visible and pressing it took the Trainer to the Catch-Up Card Packs, special Card Packs which gave the Trainer the possibility of obtaining Dragons from previous chapters.
- In case the Dragon has not yet been unlocked through leveling, the File:Unlocked at level (Gray Button).png button will be shown, indicating the level the Trainer needs to reach before being able to buy, breed or obtain that Dragon through another method. The button is grayed out and can not be pressed.
- The File:Win the battle at MOUNTAIN TRAIL (Gray Button).png button is displayed when the can not be obtained until Quest 2 (Mountain Trail) in Normal Mode is defeated. The button is grayed out, can not be pressed and will appear for most of the Dragons in the game, including even those obtained through bundles, as defeating said quest is a major story element.
Specific Codex Entry
When accessing a Dragon's Codex Entry from its Habitat, the Trainer will see most of the information above, along with the Dragon's given name, its current level, the level of its skill, its Enchantment Level, its mastery (if available), its current Dragon Collector Points and whether the Dragon is trained or not (a curved aura is displayed atop the Dragon's head if it is trained). The stats (Health, Base Attack, and Base Gold per Hour) that are seen are affected by the Dragon's level, its Enchantment Level, and whether it is trained or not.
The option to go directly to that Dragon's Habitat, as well as any of the green buttons explained above (regardless if the Trainer has or does not have the Dragon on their islands or in their inventory), will not be shown here. If the Dragon has the skill or mastery learned, the skill's icon will be shown in color, and an arrow can be pressed to view more information about the amount of damage it inflicts and what the skill does. If the Dragon has not learned the skill for that Element, the icon will be grayed out.
In this same section, the Trainer can choose to send the Dragon to the Academy by using the File:Academy Button.png option, to rename it with the File:Rename Button.png option, to move it and relocate it in another Habitat through the File:Move Button.png option, or to sell it for a determined amount of Gold by choosing the File:Sell Button 2.png option. The first button will be grayed out if another Dragon is in the Academy, while the third button will be grayed out if there are no available free, fitting Habitats. Additionally, if the Dragon Vault is present on the Trainer's islands, the first button will be replaced by the File:Vault Button.png button which is used to store a Dragon inside that vault.
