Way of Light
Heroism - After 10 seconds of not being hit, you gain a shield which protects you from 1 attack.
Making a return in GCM2 is Heroism. Passive abilities are nice because you don't need to think about them in the heat of battle. If you've come from the thief side you're probably taking Heroism because you've noticed you're taking too much damage. Stick to your Moon Whip and let Heroism take the pressure off. Or, if you're a warrior-type take Heroism and put your head down and let your opponents feel your invulnerable flurry.
