Kazimeriz shot another quick warming spell on the stubborn flying professor.
"The door seems to be sealed shut by some sort of charm or spell; something unusual that is repelling even blasting curses... perhaps if we simultaneously cast sperecanto* on both sides of the door, the spell will be weakened enough to move the door enough to get us through...?" Kazimeriz speculated.
"It would have to be done simultaneously and we'd need to act fast, and talk them through the motion to get it right... " That is, IF it even works. If not, or if the students on the other side can't cast it, we're in real trouble.
*ooc: a little tweak on two canon spells- spe= spell, recanto = recant/halt. Hope that works for y'all.
