Grants Atk/Spd/Def/Res+3. Unit takes 6 damage after combat.
Skillsets that use skill
The combat boosts that Fury grants are incredibly powerful. The six damage penalty may seem a heavy cost, but if you factor in the +3 defense and resistance, the penalty is only three damage. If you’re the target of a double attack, the boosts are applied twice, completely negating the penalty. Also important is that the damage is non-lethal: It will never reduce your HP below one, and will have no effect if you’re already at 1 HP. Fury allows many units to reverse matchups by surviving hits they otherwise couldn’t, win speed battles they would otherwise lose or hit new damage thresholds.
Fury is a useful skill on practically any unit, as it boosts both offenses and defenses without compromising anything save for the HP loss. Some skills require characters to stay above certain HP thresholds, such as Quick Riposte and Wary Fighter. Fury can hinder these abilities thanks to the HP reduction. Units that don’t often see combat, such as those with Sing/Dance are great candidates for the skill. It also boosts their already low combat stats. Fury can help units reach lower HP in order to trigger skills such as Vantage and Desperation.
Fury is tough to get around thanks to raising all stats. However the HP reduction can be exploited in a few ways. The HP Reduction occurs even if the unit can’t counterattack, therefore if the unit with Fury is melee, ranged attacks will cause them to take free damage.
