I recently had 7 power pips built up. I used a magic that uses 4 Pips, but instead it takes all my PIPS. You Guys at Wizard101 need to fix this major problem. Magic that takes 4 or 5 pips and you have 6 power pips then it should use only what it needs. The rest should remain that it doesn't USE.
We need more information. What is the school of your character? What was the spell you cast?
If the spell is not from your School of Focus, (ie a spell you spent training points for), it will consume Power Pips as though they are a single pip. Power Pips only count as two Pips when the spell is from your main school of focus.
If you want the prize, you have to build the ladder rung by rung. There are no shortcuts.
