Cannot disturb own concentration for Mysticism, spellweaving, & chiv
As described, in game there are times when you will want to interrupt your own spell in order to cancel it (by setting off a trapped box) It seems you can't do this for spellweaving, chivalry, or Mysticism spells.(you can for necromancy and magery), not sure about ninjitsu.
I tell you the truth, tis better to do 10 damage on the right target than 100 damage on the wrong target.
