The tooltip is obviously wrong, but I’m not sure what the actual interaction is supposed to be.
“Whenever you directly use Gathering Storm and hit at least one enemy you gain a stack of Wings of Lightning” - this implies you always get a single stack of Wings of Lightning regardless of points invested, leading me to assume it’s scaling how many crows benefit from Wings of Lightning per stack.
Yet, the next line is: “Each time one of your Storm Crows attacks it consumes a stack of Wings of Lightning…” - which directly implies whichever crow attacks first consumes the stack, and it’s not scaling how many stacks are consumed because it says they consume a stack.
By way of comparison, Firebrand’s node “Exothermic” reads: “Using Flame Reave consumes stacks of Firebrand to gain Ignite chance per stack consumed.” this is very clear even if the “per point” section was as vague as Wings of Lightning and said “Firebrand: 3 per point | Ignite Chance: +100%” you’d still say "oh, it’ll consume up to 3 stacks per point for a +100% chance to ignite per stack consumed just like the skill description said.
So if anyone has any idea how this node is supposed to work, I’d appreciate the explanation
