Cerberus takes about 51.8 seconds per kill in OSRS with the best setup, a Scythe of vitur doing 12.06 DPS at level-99 stats. RuneBuddy's Boss Fight Simulator runs the real phased fight tick by tick, so you get a kill-time spread for your own gear rather than a flat DPS number.
Cerberus has a scripted fight in RuneBuddy's Boss Fight Simulator: its phases, attack rotation and punish mechanics are modelled tick by tick, so kill time accounts for the downtime a flat DPS figure hides. Open any loadout below to run the fight, or see the best-in-slot gear for Cerberus.
