Autoattack: His melee attacks differ based on which arm is used, with the right-hand weapon (square blade, red weapon trail) applying Corrupted Blood and the left-hand weapon (scimitar, purple weapon trail) having 50% Physical to Chaos conversion.
Fire Flurry: Kosis fires three ground-targeted Fireballs from his left hand with a 50% chance to ignite.
Lightning Flurry: Kosis fires a zig-zagging beam of lightning from his right hand directly in front with a 50% chance to shock.
Fire Combo: Kosis imbues his weapons with a red/purple weapon effect, then quickly slashes with both weapons before throwing both of his weapons forward (dealing a large AoE hit on contact with an entity or obstacle). He then channels eight waves of three fireballs. The central fireball is larger and always ignites.
Lightning Combo: Kosis imbues his weapons with a red/purple weapon effect, then quickly slashes with both weapons before throwing both of his weapons forward (dealing a large AoE hit on contact with an entity or obstacle). He then channels eight bolts of lightning that also deal damage in a small cone directly in front of Kosis, leaving a Lightning Volatile at the targeted location.
- Lightning Volatiles: Persist on the ground and explode on contact, always applying shock as well as applying a 20% increased damage taken debuff for 2 seconds.
Demon Beam: Kosis gains 15% of his Life as Energy Shield, and channels a wide black beam at a targeted location, creating a Death Zone over 10 seconds that increases in size. Fully depleting his energy shield while he is channelling will briefly stun him, ending the skill prematurely.
- Death Zone: Applies the Chilling Vision debuff to nearby enemies within the pulse, dealing physical and cold damage over time and halves movement speed, and applies the Electrifying Sight debuff on contact with the sphere, dealing physical and lightning damage over time.
Demon Orb Detonation: Kosis drops onto a Death Zone near a target, causing up to 8 consecutive ring-shaped shockwaves to radiate outwards, based on the size of the Death Zone. Ignores walls and obstacles. The shockwaves can also cause other Death Zones to detonate and create shockwaves on contact.
Teleport Attack: Kosis teleports to a distant target before doing a melee attack, creating a small Death Zone at the previous location.
