Assuming tempest strike stay relatively close to the current version, for secondary spell.
The latest patch corrected the little pink block issues with tempest. I noticed that thoses were actually enhancing the visual clarity of this skill.
When you have stack of maelstrom, a tornado and a few monster around you each with differents effect it can be difficult to notice if tempest procced or not.
Would it be possible to add a little effect that would make it more noticeable?
I was thinking about mixing it with the lightning version of fire aura (since its a cold/lightning spell). Maybe a little more rounded in a ring shape as to not add too much lightning to a class that already have a lot of it
