Bad-el-Kazar is a Force Legendary from the Undead Hordes, filling a Support role. His appeal is straightforward: he covers three critical team functions within a single champion slot — ally debuff cleanse via Malevolence, area healing via Dark Sphere, and Poison application backed by a passive that boosts the whole team's damage against poisoned targets. That self-contained kit is why he is well-regarded at Clan Boss, where keeping allies free of stuns while sustaining health is essential, and why he is often cited for soloing high-level Dragon and Ice Golem dungeons with the right gear. His main limitation is Fire Knight, where his basic attack's AoE pattern is a poor fit. In Arena he functions best in go-second compositions, acting as a safety valve to cleanse debuffs off allies before the team fights back.
