Using the same tactic that Finwe used, Grassus casted [Thunder Step] spell to increase his moving speed to a hundred times faster and appeared behind blonde-hair Kain in less than three seconds as he casted [Storm Sword] then struck the storm sword into Kain's back attempted to electrocute him to death.

[Storm Sword], a level 40 Thunder Magic spell. This spell will create a storm sword on the caster's hand. This storm sword can penetrate through all types of armor and stun, as well as cause damage on a single target within a five feet radius. If the target enemy has weak Magical Resistance, the storm sword will be stuck in his/her body and continuously electrocuted until he/she dies. However, if the target enemy's Magical Resistance is too high, the storm sword will bounce off and cause no damage to the enemy.
