Although Dragons are playable for just a short time, the common perspective is that they function mainly as equipment for Adventurers.
Passives are the top priority, since an Adventurer does the bulk of fighting. HP is the best stat for healers, while all other Adventurers benefit from high Strength, Critical Rate and Critical Damage.
Skills, attack combos and animations are considered in the context of a Dragon’s passive. Some skills are incongruent with the stat boost, or attack animations and ranges impact damage depending on the setting.
Availability. We assume that story, event, and 3* Gacha Dragons can be reasonably unbound when playing the game regularly. For those who join later, however, event Dragons are effectively omitted.
These dragons are best-in-slot for the majority of Adventurers thanks to their ample offensive bonuses and powerful Skills.
Tier 2 Dragons either provide ample HP bonuses to healers, or balanced Strength and HP. In any case, one can’t go wrong equipping these.
A handful of strong, but occasionally outclassed dragons with special roles and Skills.
These are good options if a player is lacking in variety-- Bonuses given are of a good magnitude, and their Shapeshifts turn the tide of battle.

Dragons to sell for Eldwater. Keeping dupes of other dragons to equip in place of these is recommended.
