How about:

Initiative:  To protect his allies as if they are worth as much as a king, Chester can prepare for a incoming attack. Target allied to apple X seconds mark. If marked allied takes damage from enemy, Chester will rush to target allied, block the damage and stun nearby enemy to make an escape.

Just another idea :)
