Still one question about Astarion since I don't want to break any rule or anything. In canon, he can move under the sun freely despite being a vampire (and can cross rivers AND enter houses without explicit invitation) due to something that's been implanted in his head.

I am writting my TDM assuming he's moving around with the sun already setting, so no direct rays to annoy him and I 'buy' myself time to wait for a reply but: I am to assume he is just as vulnerable as his usual self, right? No regeneration and all vampiric perks are A Thing already in his world, since the thing in his head disabled it, but I'm assuming the Good things from it also don't count anymore.

It's also worth asking: he's still going to feel the thirst ffor blood and weakness if he doesn't drink it, right?
