Blade Tempest is an augment skill on branch 2 of Amon's Cybernetics skill tree in Borderlands 4.

Effects

Amon now readies Forgeswords, choosing Flame or Shock. Whenever activated, consume all Charges to launch a Barrage of Forgeswords.

Enemies damaged by Forgeswords are Primed for a Duration, and will Detonate when they die or are damaged by a Forgeskill dealing Damage to the target, but none to nearby enemies.

Can fire a Barrage of Flame Swords, dealing Incendiary Melee Damage, or a Barrage of Shock Swords, dealing Shock Melee Damage. This effect can stack.
