Brinerot Flag grants no mana on spell hit

If I am correct, then Brinerot Flags

"Gain +3 Mana when you hit a Taunted Enemy"

should also count for spells, since it does not specify a hit by an attack. I have tried this using Litghning Ball + Abyssal Cry as well as Firestorm + Decoy Totem, yet no mana seems to be gained.


Either this is a bug, or the wording is incorrect.

I hope I helped.



PS - I also hope this is a bug, not gaining mana on the spell hit ruins my build :(
