remove the ability to stun from the ghost's spell decks:
Why?
since you can only hit during medicine mode
and since medicine mode is only one round
When they stun you right before medicine mode you cant' hit
and now you have to stand there for 5 more rounds, doing nothing - meanwhile all your boosts are now gone as they remove them all after medicine mode.
Trying to make a Wizard101 version of Pacman was a cute idea, but not very well thought out. In the real pacman you get more than 1 second to chase the ghosts - and if you eat them they go to time out briefly.
You can just Stun Shield or Conviction and avoid the stuns completely. The real problem is when they -90% you right before the Medicine Mode round; now THAT is annoying.
