Neve stared at the spell she'd just created.
{Fireball}
{New: Fireball now deals an additional 16% max HP damage}
She blinked twice. Her hands were held up, high in the air, almost in the same position one would get into if someone was pointing a gun at them. She stared at this message for a while, unable to actually process what she'd made.
Finally, after staring at the message for almost half a minute, she said:
"T-That's insane!"
16% Max HP damage on a spell that cost 10 mana was... Not balanced.
Granted, the amount of damage the spell did could still end up being reduced by the enemy's armor or the enemy's natural resistances. She was likely never going to get the full value of this spell when fighting bosses and minibosses.
Against regular mobs, however? No, those would likely never pose a threat again, unless Neve ended up {Silenced} somehow.
