Arena’s Claws

- Unlock: Complete Sealed God Main Story Quest
Activating Arena’s Claws summons giant whirling claws that slowly move forward, dealing damage to any enemies in range. The power causes heavy damage to targets and can hit multiple enemies in a straight line, making melee combos even deadlier.
Crystal Blast
- Unlock: Defeat Aramon’s Power Source
Summons a cluster of dark orbs that scatter across the battlefield to explode on impact. The attack is best used when Kaser is surrounded and is one of the best AoE abilities in the game. It can also apply the Electrified status ailment after upgrades.
Stellar Guardian
- Unlock: Defeat Victor
Using Stellar Guardian creates orbs of energy around Kaser for thirty seconds, damaging any enemy coming in contact with them. Although the damage dealt by the orbs is minor, their attacks at close range help chain together combos without disrupting the flow of combat.
Frost Blast

- Unlock: Defeat Lord Golden Lion
A top-tier Arena Power that allows Kaser to plant a landmine at his position. When an enemy comes into proximity of the trap, it explodes in a wide area, afflicting targets with the “Frost” status ailment. Both bosses and minions can be lured onto the mine, and the subsequent explosion shreds health and shield bars.
Heavenstruck Wood
- Unlock: Defeat Squall
Summons a magical tree that deals lightning damage to all enemies within a medium radius around it, functioning like an AoE turret. It also applies the “Electrified” status ailment to any targets hit.
Lifeforce Bestower
- Unlock: Defeat Buckhorn Spirit Dragon
Summons a magical tree similar to Heavenstruck Wood. However, instead of a lightning attack, the tree heals Kaser within its area of effect. The Lifeforce Bestower is the only Arena Power dedicated to healing. When healing potions run out and Liana isn’t nearby, the Lifeforce Bestower becomes crucial.
Mountain Break

- Unlock: Defeat Rose Queen
Three rows of Voidrax energy erupt from the ground in the direction Kaser is facing. The attack has immense AoE and is extremely effective at crowd control, its snappy casting time adding to the appeal.
Manifestation
- Unlock: Defeat Ancient Mecha
Summons an ancient spirit from Lord Arena’s memories. The summon acts like a turret, damaging enemies within a large radius for thirty seconds while remaining stationary. While the damage is low, it is consistent and can be increased by upgrading the power.
Purgatory Dance

- Unlock: Defeat Arena’s Phantom
Kaser spins in mid-air and unleashes a hail of slashing attacks on any enemies in front of him. The power is ideal for dealing burst damage to a single target and fits neatly into a combo chain with its flurry of attacks.
Voidmaw
- Unlock: Starting Arena Power
Obtained after freeing Lord Arena, Voidmaw launches a dark projectile that can strike enemies over long range. Upgrading the power allows it to restore Fusion Energy. It’s a valuable power early on, when ranged attack options are limited.
