Can a crossblooded sorcerer take the unique bloodline alternative capstone?

[Maniacwyrm]

So i want to make a sorcerer with as many bloodlines as possible, aiming for 4 with crossblooded, unique bloodline and then the eldritch heritage line of feats. Is this acceptable by the rules?

It doesnt really matter that it might not be super optimised i just want to know if it works

I'm going to have to lean (heavily) towards no. Crossblooded specifies that you must choose between the two powers available to you at the levels you receive them. The Alternate Capstone ability: Unique Bloodline is trading away that 20th level bloodline power, and isn't a 'new' bloodline power in which you choose from.

I would certainly allow it at my table, in either case.

I don't see why you couldn't take the Unique Bloodline.

Crossblooded doesn't trade away the 20th-level bloodline power, it just lets you choose between two.

It is an order of operations issue. Some people will look favorably on reading it one way or the other. I take the most strict reading when I review the RAW and that rarely allows for shenanigans to ensue. However, I don't follow RAW strictly in the games I run, which is why I said I'd allow it.

I didn't answer this question in the Rules forum because I didn't want to get into the gritty specifics of the issue.
