Blood Boil Warlock

SummonCasterHybrid

A unique summoner-caster hybrid that sacrifices demons for massive AoE explosions. Blood Boil detonates your summoned demons, dealing fire and physical damage in a wide radius. Combines demon army management with explosive burst damage.

Pros

  • +Massive AoE burst from demon explosions
  • +Fire + physical hybrid damage handles most immunities
  • +Unique and satisfying "summon and explode" playstyle
  • +Moderate gear requirements — no extreme runes needed

Cons

  • -Must constantly resummon demons after Blood Boil
  • -Lower sustained DPS — burst-oriented playstyle
  • -Demon management adds complexity vs pure caster builds
  • -Less efficient than Fire Chaos for speed farming
