How does Grisbow's Enraged Mode work?

Once Enraged, its skills deal 30% more damage and its EP recovers 25% faster.

Rage builds three ways: attacking, taking damage, and spending EP on skills. Rage also pays off before the switch flips, because attack speed, damage and resource recovery all climb as the meter fills. The two bonuses also feed each other. Faster EP recovery lets you cast more often, and every cast adds more rage.

If you want the state right away, use Rock Smash. The ultimate generates 100 rage immediately and puts Grisbow straight into its enraged combat state, so you skip the build-up.

Which skills feed the rage

Grisbow's claw skill is Fanatic Clawing in its base form and Claw of Madness in its Prismana form. Both cost 10 EP, have 40 power, and run on the same Rage and claw-mark mechanics, so switching forms does not change how you play it. Fanatic Clawing can stack up to 12 Claw Marks on a single target, which suits fights where you stay on one enemy.

Cheap 10 EP casts that build rage, plus faster EP recovery once Enraged, make a simple loop: keep clawing one target, let the meter fill, then cash in the 30% damage bonus.
