Practice Field (3.5e Spell)

''Watching in the stands, you are ready for the magical duel to begin. A performer comes out, and you hear instruments playing her a royal tune. She dances for awhile swinging her body gracefully to the melody of the tune. Right at the end she performs a jumping move, jumping extraordinarily high, and casts this spell. At the top of her jump, a sphere erupts above her, and extends to take the size of the field.''

You create a sphere that has a maximum radius of 5 feet per caster level, though you may voluntarily lower its radius. In that sphere, any creature may choose to make its attacks deal nonlethal damage.

This spell can be made permanent via the Permanency spell. It costs 1000 experience points and you must have a minimum caster level of 10 to do so.
