Ashe's Mind Lance (3.5e Spell)

Developed by Professor Ashe to keep troublesome students from interrupting her classes, this spell creates a powerful stabbing pain in the head from a small sliver of force, which makes casting any spells extremely hard.

This spell causes a creature within Close range to have difficulty casting or concentrating on spells for a time. Should they fail their Will save, for the duration of this spell the creature suffers 1 point of damage each time they attempt to cast a spell or maintain concentration on a spell. This damage prompts a concentration check for the spell being cast, but the DC is increased by the caster level of the person who cast the mind lance. If this check is failed the spell is lost as normal, as are any limited resources used to power it.

This spell may instead be cast as an immediate action, as a response to a creature beginning to cast a spell. In this case, the target is granted a save as normal, but if they fail they are affected as above with an additional +10 DC penalty on the concentration check. When cast in this way, the mind lance lasts only until the start of the target's next turn.
