Upgrading one of my spells

i a also changing the Name. On my current magic list it is called Finishing Bolt)



Name: Catastrophe Blast
Rank: Rank C (Signature Spell)
Type(s): Offensive
Element(s): Lightning/Darkness
Duration: Instant
Cool-Down: 2 Post Incress cooldown please to at least 3
Damage: N/A, Adds one rank of damage to the current attack. (This attack stacks with any other effects)
Effect: Any target hit by this reduces their speed by 1 rank for their next post ok so this is ok but the 1 rank lower would only effect C ranks but you could have a B rank reduced by half a rank and a A rank 1/4 rank any higher would not be effected, as their muscles lock up fro the electricity flowing through their body.
Description: The caster channels his power into an attack and as he lands the strike, he focuses all his charged energy into the part of his body hitting the target. As his attacks connects with the target, a bolt of lightning comes crashing down to hits the target at the same time.

Strengths:
*Damage - This spell is meant to immensely increase the damage of a attack.
*Speed - This spell is almost instant, so if the base attack hits, then this spell is pretty much guaranteed  to hit.
*Stacks - This spell's effect stacks with any effects that already increase the damage of an attack (such as already existing increased strength, etc...)

Weaknesses:
*One Target - This spell only effects one target.
*Melee - This attack is required to be added to a melee attack. So the caster has to be able to land a kick or punch to even do this attack.
*Redirecting - If there is a lot of metal somewhere near the opponent or if the opponent can create metal away from themselves, the attack will be redirected.
*Grounding - If someone can find a way to ground the attack onto earth, or change the element of their body into earth, this spell does nothing.
