Vitality Mantle - How To Use
Useful Against Enraged Monsters
Equipping the Vitality Mantle allows the user to absorb one health bar's worth of damage. This is especially useful against enraged monsters as they prevent the user from immediately going to a faint state.
Recommended for All-Out Attacks
During the duration of the Vitality Mantle's effect, provided that the hunter has yet to receive a significant amount of damage, going for an all-out attack against a Monster is a recommended strategy.
