Thank you. I didn't think there was any reason for them to not stack, but wanted to double check to see if there was a rule I was missing.

If a wizard or sorcerer has multiple effects that increase the effective caster level of spells with certain descriptors, do these increases stack with one another.

For example, lets look at the spell Burst of Radiance. 2nd level evocation with the light and good descriptors. If this spell is cast by an elf with the alternate racial trait: lightbringer (treated as one level higher when determining the effects of any light-based spell or effect they cast) and the campaign trait: Force for Good (good-aligned spells are especially powerful, and they function at +1 caster level.)

Does this character cast the spell at caster level +2 or do the effects not stack?
