Unlike other commanders, you take no attack penalties for fighting in heavy armor. (As indicated on your class chart, your base AC in heavy armor is 14.)
When an enemy misses you with a melee attack and rolls a natural 1 or 2, you gain 1 command point.
Once per day as a free action when you are hit by an attack that targets AC, you can take half damage from that attack instead.
Once per day as a free action, you can gain a bonus to AC equal to the current escalation die until the end of the battle. (The AC bonus increases or decreases as the escalation die increases or decreases.) This bonus can’t be higher than the number of icon relationship points you have with warrior or leader icons in your game.
