Causes the bones inside a target to pulse painfully, bestowing -2 to attack rolls, universal saves, skill and attribute checks and knocks them off-balance for 1d3+1 rounds. If target was already off-balance, then knocks prone. If caster has greater spell focus: necromancy, statuses instead linger for 2d3+1 rounds.
