Duration 1 minute/level (D)
Saving Throw none; Spell Resistance no
For the duration of this spell, a wizard or sorcerer divides his consciousness into two entities that are both capable of normal mental activity. Basically, the caster doubles his normal actions except where his actions would be limited to having only one body and one mouth. The caster may move and cast a spell at the same time with each of his minds directing one of the actions, but if the caster takes a move action while his second mind is casting a spell, he must make a Concentration check at DC 15 + spell level to succeed at the casting.
For example, a wizard under the effect of dual mind might move his normal rate while casting magic missile with his second mind. The magic missile would require a Concentration check at DC 16. Then, in the second part of the same round, his first mind, which directed the move, might cast haste, while his second mind took its move action. The haste would necessitate a Concentration Check at DC 18.
The wizard could not, however, cast both spells and then try to take two move actions, since he would be attempting to perform actions that required his one physical body and mouth to perform two different functions simultaneously. Since haste and magic missile have verbal and somatic components, the wizard cannot perform both castings simultaneously.
Because his consciousness is divided and unfocused while under the effects of this spell, the caster receives a –4 circumstance penalty to saves versus mind-affecting spells and effects.
