Infelizmente, o vínculo divino não se acumula. Apenas magias e energia do canal.
Spells per Day: At the indicated levels, a vindicator gains new spells per day as if he had also gained a level in a divine spellcasting class he belonged to before adding the prestige class. He does not, however, gain other benefits of that class other than spells per day, spells known, and an increased effective level of spellcasting.
Channel Energy (Su): The vindicator’s class level stacks with levels in any other class that grants the channel energy ability.
