Moveset

Key	Move	Preview	Description
Z	Incinerating Blaze Mas. 1	▶	Pressed, a fast violet fire shockwave damages and sends enemies forward flying. Held, a violet flamethrower shoots from your hands, controllable by turning, similar in spirit to Empyrean's Z and Fox Lamp's X.
X	Hellburst Impact Mas. 50	▶	Pressed, you condense violet fire into a large orb launched forward that damages on impact. Held, the orb stores more energy - it becomes larger, faster, and hits harder.
C	Infernal Execution Mas. 100	▶	Charged with violet energy, you dash toward the cursor - on contact, the target is trapped in rose energy, you teleport behind it, then strike with a devastating blow that deals damage and sends them flying.
V	Transformation Mas. 300	▶	A roar erupts with spikes from the ground, dealing damage and sending nearby enemies flying, then you transform into a massive Fiend with glowing rose eyes. While transformed, a rose mist surrounds you and you lose access to fighting styles, swords, and guns.
F	Abyssal Rush Mas. 200	▶	On the ground, you charge and grab the enemy to slam them twice into the ground between energy explosions and violet spikes before sending them flying. In the air, you grab them, spin, then throw them - slightly less damage but much faster.

Transformé

Key	Move	Preview	Description
M1	Normal Attack	▶	A combo of energy claws concluded by a spinning uppercut that launches the target into the air, followed by a sharp downward strike that creates a large area impact.
Z	Incinerating Blaze Mas. 1	▶	Pressed, the violet fire shockwave is even faster and hits harder. Held, the flamethrower grows larger and burns continuously - you control it by turning and gain super armor that blocks all knockback during the move.
X	Hellburst Impact Mas. 50	▶	Three versions - pressed, a large violet fire orb hits hard on impact; held (tier 1), it becomes larger, faster, and more painful; held (tier 2), it transforms into a massive energy sphere with huge damage in a wide area.
C	Infernal Execution Mas. 100	▶	Same execution as the base version but more powerful - propulsion toward the cursor, target trapped in rose energy, teleportation behind them, then a charged energy strike that deals heavy damage and sends them flying.
V	Transformation Mas. 300	▶	Return to normal form, which restores access to fighting styles, swords, and guns.
F	Abyssal Rush Mas. 200	▶	On the ground, a very fast charge grabs the enemy and slams them twice into the ground between explosions and violet spikes before sending them flying. In the air, the target is trapped in a magma sphere while you spin before throwing them away.

Transformation

When transformed, you gain 34% damage reduction, approximately +25% speed and cooldown reduction, doubled jump and dash, water walking, and a super dash (5s cooldown) that grabs enemies in its path.

Skins

Fiend has two skins, according to the source's Fiend/Skins page:

Skin	Rarity	Obtainment
Red	Common	Default look, unlocked with the mutation itself (1,500 Robux in the Yeti mutation section, or 3,999 Robux in the Raging Frost Bundle).
Runic	Mythical, CHROMATIC skin	1% chance per Summer 2026 Chromatic Box; the source's Skins page adds that it is guaranteed after 100 boxes opened.

The Runic skin arrived with Update 30 (Sea 1 Rework, 5 September 2026). It changes the whole transformation model, which the source presents as a first shared with Arcsteel Magnet, and it was originally named "Sealed Fiend" (trivia added by the source on 28 September 2026). Fiend is the second mutation to get a skin, after Empyrean.
