A tree taller than the caster.
Touch tree with both hands and repeat x5 "Open up and receive a loyal protector of the forest."
Caster is assumed to be inside the tree, and may not be attacked. May cast Verbal Magic, but must touch the tree or the spell ends.
If the tree is hit 10 times by a slashing weapon, or if a flame effect strikes it, it is destroyed and the caster is no longer protected. The caster may not fight with weapons while the spell is in effect. The caster may be affected by Verbal Magic while he is casting magic.
