Magus ringChaos Elemental has a scripted fight — see Chaos Elemental kill times in the fight simulator to run these builds through the real phased kill tick by tick.
Assumes level-99 combat stats and the best relevant prayer and potion, off Slayer task (no Slayer-helmet bonus). DPS is single-target on the boss's base stats; magic setups consider powered staves. Numbers come from RuneBuddy's WASM combat engine, the same one behind the DPS calculator.
