"Surprise!"
Arcane traps can be placed with a spell.
"Blink" is done as well. It will probably be a late game spell since it's rather powerful.
It allows you to slip through prison bars, portcullises and even cracks in the wall by teleporting you just a few feet straight ahead.
Wizard's Eye should be interesting to fully implement.
For the moment, I'll try to limit myself to spells that are actually useful within the alpha area.
