OSRS Mobile - The Bane of Demons Combat Achievement

Not 5:0 - simply face tanking K’ril and his bodyguards.
NOTE: I don’t suggest Purging Staff when face tanking the hits, I would recommend Toxic Staff/Staff of the Dead because of the special attack which reducing incoming melee damage from all sources.
That + Ward of Arceuus makes this task 100% brain dead.
Only reason I face tanked K’ril was because I wanted to see if Purging Staff was strong/accurate enough to finish K’ril effortlessly (WHICH IT’S NOT). Either way, thank you for watching!
