Buff Gems

These are probably on their way as they seem nigh inevitable but I thought I'd post them as an idea anyway.

Buff Gems enhance stats like str, dex, cnc, int, agi, cnt, for a few ticks in battle. Can be single use versions and multiple use versions.

There could be more complicated buff gems (such as reactive or volatile buffs), but for now I'll stick to the basics.

It might get difficult to keep track of all your buffs (at some point), however, so it would be nice to add graphical buff icons (could simply be a copy of the gem icon iteself with a mouseover that says what it is) in the corner of the battle screen to indicate which buffs are actually "on" you.
