Spells per day for PrCs

[Andrea1]

I am currently a cleric going into Holy Vindicator and am wondering about the spells-per-day description. Do I lose out on domain spells and domain powers when I level as a HV instead of Cleric when I achieve another spellcasting level.(First level of HV gives no spellcasting levels but the second one does.)

My understanding is that if it says "+1 Divine Spellcasting" (or equivalent), then you would go back to the spells-per-day of your base divine caster class and use that. And, for cleric, that chart includes the +1 for domain spell.

However, your domain powers are not spells, they do not improve unless the class has a feature that indicates they do so.
