Destabilize (Physical, Debuff) (300): In an instant, Somerled pulls magic out of his very form, causing it to destabilize, and forces it into the enemy with a strike. The unstable magic causes agonizing illusory pain to course through the target’s body for a second. This pain hallucination results in their muscles seizing up, interrupting their current action suddenly and painfully. While the pain itself won't leave any lasting physical damage, because it's entirely imagined, the experience of such an intense level of pain might freak people out. Being destabilized himself, Somerled is unable to channel magic efficiently, doubling the cast time of all his spells and making his general movement use twice as much energy. This effect lasts until his body stabilizes again, after 15 seconds. As an instant-cast spell, the charge can't be held on to, and must be used as soon as it's activated. Missing the strike doesn’t use up the magic however, and it's returned back to his body, stabilizing it immediately.

Changed version here.
Halved the length of Somerled's debuff and changed it. Instead of lowering his defense, it makes him a lot more inefficient for a while.
