Regular Player cards have 1 active skill and 3 passive skills.
Certain Special cards (such as penguins, gatekeepers, and boss minions) can have less than 4 abilities.
Each skill can be upgraded to the maximum level of 5.
You get a skill point when the card reaches levels 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65 and 70 as well as when the card gains a superb power-up (through training with a duplicate card or using the gatekeeper Littre).
Skills that say "within the position", frequently known as "totem" skills, apply to players in the same horizontal line (Forward, Midfield, Defensive lines). Skills that say "within the vertical line" are totem skills that apply in the column of the player with the skill. Buffer skills affect all ally players in the same line as the player with the skill in addition to the player themselves. Debuff skills only affect all enemy players in the same line. However, some totem skills affect the entire ally/enemy team.
Totem skills that require an action to proc will also affect the next line if the player moves forward and meets the requirements to proc the skill. Note: using the active skill does not count as an action.
Totem skills with the same name do not stack unless one skill is the upgraded/evolved skill. Example: Honorable Vow I and Honorable Vow II do stack.
