Feat
Word of Power
Makes a spell strike harder than its level allows
Every damage-dealing spell gains fixed bonus damage equal to the caster's Intelligence + Charisma.
Apply the bonus once per spell, not once per target or die. Add it after normal damage is calculated, whether the spell affects an area or fires a single ray.
This is a flat bonus: it does not scale with caster level. It carries great weight at low levels, where it can double a minor spell, and becomes proportionally smaller as spell magnitude rises. A Lazy Wizard who has developed both mental attributes nevertheless retains a permanent measure of power no chart ever granted.
