Tis a simple game. I give you various challenges (i.e. quest bosses) and you must create spells which meet certain requirements and restrictions to defeat them. Here's the first:
A 7 feet tall, leather cladded barbarian is charging towards you, less than 50 feet away. His skin has been magically toughened to be impervious to most projectiles, and the enchanted two-handed axe he is swinging delivers enough kinetic energy to shatter stone.
Spell requirements: must not be mind-affecting, must not involve fire or electricity, must not create something out of nothing
Remember that the idea is to DEFEAT the boss. Teleporting away won't cut it.
After a really creative response I will reset it with a new, stronger boss and new requirements.
