Acheron
Who is Acheron?
Acheron (true name Raiden Bosenmori Mei) is a 5★ Lightning DPS of the Nihility Path and, as of Patch 4.2, a top-tier Ultimate-driven hypercarry — source: Prydwen. Instead of a normal energy bar she builds Slashed Dream stacks whenever debuffs are applied to enemies, then unleashes a devastating Ultimate.
Kit Summary
Builds Slashed Dream stacks from debuffs applied by the team (no normal energy bar); at max stacks she casts her Ultimate.
Slashed Dream Cries in Red removes Crimson Knot stacks for enormous single-target (Rainblade) and AoE (Stygian Resurge) Lightning damage.
Her A4 trace The Abyss scales with the number of Nihility allies — she demands a debuff-heavy Nihility lineup.
