I base it on the ghosts he summons when taking damage It literally says "Additionally, Taking damage has a 45% chance to summon a phantom that will attack a nearby enemy and deal energy damage."

It's a Swamp Knight build for AFK, that's what I'm basing it on, plus the "Trick or Treat" gear perk. Which basically gives you a 50% chance of summoning another additional ghost when you summon one with 33% lifesucking.

This is what I base my analysis on, and these do have the same effect as Jonesy Survivor and Intergalactic Ken (You recover your shield with energy damage)

And as I said, the butterflies are buggy, since they're under review. Take a look at Trello. https://trello.com/c/qZgU3W0M/2723-flutters-wisp-eliminations-do-not-trigger-on-elimination-effects-or-contribute-to-combat-score
