power usage when craftingFollow

ive started to notice, since ive pretty much had to get from 0 to 19 all alone, that when you skill craft your power, or as i still call it "mana" goes down. my two main toons are a high elf templar, and a iksar necro... are there any buff you can think of that buff my power? so that i pretty much don't run out of any when i'm crafting.

or is this even something to worry about.

thanks in advance
