'Mental tremor spell, up to rank 4, limited to the darkness element. Focus your mental energy into a shockwave to destabilize or destroy the opponent's mind. The shockwave shoots from the eyes so an excessive use will stress that organ.'
'This can be extremely useful in battles against humans, I don't know its effectiveness against magical beasts though.'
As soon as he read the effects of the spell, Noah could already identify its strong points and weaknesses.
'It should be pretty effective against cultivators with a weaker sea of consciousness than mine while it should at least disorient those that are on my level. Its strongest quality is that it's hard to defend against mental attacks while its weakness it's the necessity of looking at my enemy's head. Overall, it should be a pretty reliable spell.'
Noah was satisfied with the spell, he wasn't expecting less from something limited to the darkness element.
