The Aggression Zone
The Arena's Aggression Zone has an effect on those combatants within it. Any combatant within the Aggression Zone receives a +1 to all Attack rolls and a -1 to all Defense (to a minimum of 0). This is called an aggression modifier.
If a combatant remains in the Aggression Zone for a second round, they get +2 to Attack rolls but -2 to Defense (to a min of 0). A third round increases it to +3/-3. But the bonus/penalty doesn't increase after that. If the combatant returns to the Aggression Zone after leaving it for a round the bonus is reset to +1/-1.
Immediately upon entering or exiting the Aggression Zone a combatant may take their turn as normal. Movement into or out of this zone is considered a free move. Further important information can be found in the section, "Turn Option: Change Zone".
Being in the Aggression Zone does not affect Tech rolls.
