There are a lot of status effects in the game.
Blinded enemies cannot perform standard attacks.
High Combo just means it's a attack which will result in a high hit counter, which allows you to procc chases with 10 hit combos (Sasuke, Karin) easier.Poison: Affected ninja will receive damage at the end of the turn. Poison can be stacked up to 4 times (damage will be added together)
Ignition: Affected ninja cannot be healed, will receive damage at the end of the turn.
