Mind Bolt is an Enchanter spell.
Throws pale phosphorous light at the enemy, it's a simple mind attribute magic that deals damage to the enemies body and mind at the same time. Though the damage is low, it has the additional effect of slightly decreasing the MP of the target it hits.
In the novel it's described as, "a pale magic arrow" and, "an arrow of psychic power that could go right through single enemies." 
Although the damage of this spell is passable for an Enchanter, the effect is plain and the feeling of "I should be using support magic now" makes this this spell not stand out.
