Focused Caster (3.5e Feat)
From D&D Wiki
Focused Caster [General]
A caster has spent so much time training in casting and neglecting other aspects of combat that the skills of the spellcasting have improved greatly.
Benefit: Spellcaster adds +1 to all save DCs on spells. Additionally, for every +4 modifier in the spellcaster's primary attribute, the caster will add 1d4 to the damage or healing effect of all spells. For example, if a wizard has an Intelligence of 18 (+4 mod), then he will add 1d4 to every damage spell he casts. If his Intelligence is 26 (+8 mod), then he will add 2d4.
