É possível obter um recurso semelhante ao Warmage Edge sem se tornar um Warmage?

Estou nivelando um feiticeiro npc, que acompanha os PCs. Ele se concentra no uso da magia do fogo.

Eu realmente gostei do recurso de classe Warmage Edge e gostaria de saber se existe alguma característica similar, que pode ser obtida por um talento ou item mágico, mas seria baseada em carisma e afetaria mais do que "apenas magias de guerra". Eu estava esperando encontrar algo em Complete Arcane ou Divine, mas infelizmente não havia nada.

Warmage Edge (Ex): A warmage is specialized in dealing damage with his spells. Whenever a warmage casts a spell that deals hit point damage, he adds his Intelligence bonus (if any) to the amount of damage dealt. For instance, if a 1st-level warmage with 17 Intelligence casts magic missile, he deals 1d4+1 points of damage normally, plus an extra 3 points of damage due to his Intelligence bonus. The bonus from the warmage edge special ability applies only to spells that he casts as a warmage, not to those he might have by virtue of levels in another class.

A single spell can never gain this extra damage more than once per casting. For instance, a fireball deals the extra damage to all creatures in the area it affects. However, if a 3rd-level warmage casts magic missile and produces two missiles, only one of them (of the warmage's choice) gains the extra damage, even if both missiles are directed at the same target. If a spell deals damage for more than 1 round, it deals this extra damage in each round.
