Yea like they^ said:
-Long range magic attacks.
-Used by INT based chars.
If your char is STR based then nukes are pretty much useles for you.
They will do nothing but leech your MP, and STR based chars dont have much of it

So its a waste of SP and potions.
If your character is INT based then go ahead and add nukes :] You have enough MP to use them and of course they will do a really good dmg.
Incase you dont know what "STR" and/or "INT" means:
STR: Strength(HP)
INT: Intelligence(MP)
