This is a complete list of all cards that can be used in different Dokkan Events and Prime Battles which can give you an advantage over the boss.
This can be due to various reasons:

  • Link Skill
  • Passive Skill
  • Card (character) itself

The effect is also different:

  • Deal more damage
  • Disable, bypass or weaken the boss' Passive skill
  • Recover HP

The list for Prime Battle consists of cards that are only freely obtainable (free cards that can't be purchased by any means)
