Bug when using Tempest shield and Shield charge

That's very strange! I'll look into it.

Edit: Okay, it seems that any gem in the Shield causes the shield to re-eqip, making the buff drop off because you don't have a shield for a brief second. Auras seem to get around this, so I'll make sure the same tech from auras is applied to Tempest Shield.

Sadly it won't be a short-term fix, it'll be a polish thing in future! Sorry!
