Certain attacks imbue the victim with status effects that affect them for several turns. The character's statistics determine how individual status effects will affect them. For example :
Freezing stops a participant from acting
Poison slowly drains their health, and
Burning continuously causes fire damage.
All statuses have duration stacking but not intensity stacking. What that means is that an attack that can cause 5 Turns of Poison, will cause 10 Turns of Poisoning, if cast successively 2 turns in a row.
