Skills
Aya's Parasite Energy abilities — how awakening and casting works, and what each offensive skill actually does in a fight.
Aya's mitochondria let her wield Parasite Energy (PE) — the skill points earned from defeating enemies. Spend accumulated EXP in the status menu to permanently awaken a new skill, then spend MP to cast an awakened skill in battle. Skills unlocked this way carry over into Replay Mode at a reduced EXP cost.
Pyrokinesis
Offensive PE — FireA ranged fire blast, most valuable against enemies that are only vulnerable the moment they surface or expose themselves — Divers popping out of the water to strike are a textbook target.
- MP per cast
- Focused single-target hit
- Cheapest offensive skill to cast, so it's the one you'll spam most
- Doesn't hit anything beyond its target — no splash
Combustion
Offensive PE — Fire (Area)A wide fiery burst rather than a single-target bolt — the go-to answer against Scavenger packs and other enemies that swarm in numbers instead of engaging one at a time.
- MP per cast
- Wide-area damage that hits every enemy caught in the burst
- Wipes out an entire pack in one cast instead of picking targets off one by one
- Lower damage against a single target than a focused fire skill
Inferno
Offensive PE — Heavy FireA stronger fire skill than Pyrokinesis, effective on armored fliers like the Neo Ark Beetles — especially devastating paired with the AS12 auto shotgun's own fire-based rounds.
- MP per cast
- Highest raw fire damage of the three offensive fire skills
- More likely to stagger or critically wound armored targets
- Highest MP cost of the fire skills
Necrosis
Offensive PE — PoisonInflicts a lingering poison aura rather than direct impact damage. Beyond the damage-over-time, it interrupts enemy regeneration and strips active camouflage off cloaked enemies like the Stalker.
- MP per cast
- Poison damage-over-time that keeps ticking after the cast lands
- Interrupts enemy regeneration
- Strips active camouflage off cloaked enemies
- No burst damage on impact — the payoff comes from the poison ticking, not the initial hit
Heal
Support PE — RestorationA direct HP restoration skill — the reason you can go several fights without touching a Recovery item, as long as you keep enough MP in reserve.
- MP per cast
- Instantly restores a chunk of HP
- Doesn't consume a healing item
- One-time burst, not ongoing — you have to recast it every time you need HP back
Regenerate
Support PE — RestorationA sustained regeneration effect rather than a single burst — cast it before a drawn-out fight or a long stretch without a save room, and let it passively cover the chip damage you take along the way.
- MP per cast
- Gradual HP regeneration for a duration instead of one lump sum
- Lets you keep fighting or exploring while it ticks instead of stopping to heal
- Weaker total HP return than casting Heal outright if you can afford to stand still
