Recommended Substats

Effect HitRanged DMGCrit Rate

Imposter Captain Tennille is an SR Special Barnacle channeler. Dark Blue Moon vortices apply Barnacles while Power Absorption doubles down on stacks, and ally Debuff Proficiency aura is the quiet team value. C-tier overall — the channel Ultimate is awkward and damage feels soft compared to Koichi or Cioccolata Specials.
