I think it would be a good feauture for level 10+ to convert their normal pips into power pips.
This would be very useful for high pip spells (like 10 pip) to convert normal pips into power pips
I know there is gear to increase power pip chance but this could be useful for people that are low level or don't like to farm bosses for gear.

First of all, you won't need to use rank 10 spells at that lvl unless you are going for one in a million. Second of all, I'm pretty sure empower/ donate power does that already if you have 7 pips but I could be wrong.
