Orc Bloodline Power of Giants and Enlarge Person (Do They Stack?)

[shaxberd]

The Orc Bloodline Power of Giants specifically makes you Large size whereas the Enlarge Person spell increases your size one category so it seems like you should be able to stack the two effects to become Huge. I'm just wondering if maybe they don't stack because they're both size bonuses?

Multiple magical effects that increase size do not stack.

AFAIK since Power of Giants is a spell-like ability, it does not stack.
