The Mana Strike nodes Teleporting Strikes and Mana Storm are not behaving as describe when used in conjunction. Mana Storm reads, “Mana Strike additionally strikes enemies it hits with Lightning…” In practice the lightning arcs out from the player so if you’re using Teleporting Strikes and target an enemy outside of the arc range then no Lightning is triggered. Based on the description I would expect the Lightning to strike the targetted enemy and then arc from there.
Either this is a bug or I think the description should be updated to indicate that it arcs from the player. I’m not sure which since I don’t know if this is the intended behavior.
