Mobile Defender

Some train themselves specifically to aid their allies when they are being attacked, intercepting said attacks for those who do not take hits so easily.

Rush to the Rescue: Outside of your turn you can move up to your move speed as long as you end your movement adjacent to an ally.

Take the Hit: If an adjacent ally would take damage from an attack, you can spend 5 Stamina to take the damage from the attack roll instead, choosing which part of your armor it hits as normal.

Unhindered: Once per encounter you can ignore any speed reductions that would be applied by your armor or any penalties being applied to you which affect move speed for a number of rounds equal to your Agility.

Jaunt Back (Sword/Polearm Technique): Spend 2 Stamina after making an attack roll to be able to move 1 square away from the opponent you just hit. This can be used outside of your turn or if you've already exhausted all of your movement on your turn.
