The greater the value of this statistic, the more likely your character is to go first in a turn of combat. Generally, the character that starts combat gets an action and then all critters that are involved in that combat are sequenced (get it) into a list. The critter with the highest Sequence value goes first on the list, and it works its way down from there. A high Sequence does not mean that a character gets to go multiple times before slower Sequenced characters. The larger the battle, the more opponents, the more valuable this statistic becomes. As new critters are added to a battle, they will be sequenced in according to their Sequence statistic.
