If the ring idea doesnt work you could add a vial shape or a smaller circle to the other side and Havana mana in there, it would resemble a mana pot of sorts. Anyways best of luck chief.

Wtf is all I can say after that. That was all for playing computer games? Well then I'm sure everyone here would be fucked in that case. I'm very glad that guy is my dad.
