Energy drain monsters often get temp hp too (see the wight).
Erm, yes I know. That's a standard feature of 3E energy drain.
Anyway, that blood drain seems fine.
So that's settled.
Reworking Children of the Night seems next.
I'm thinking we make it all-arachnid and match the CRs (more-or-less) to the Children of the Night creature's. Plus, I fancy adding some Spider Swarms in there too, e.g.:
Children of the Spider Queen (Su): Drow vampires command the monstrous arachnids of the world and once per day can call forth 1d6+1 spider swarms, 1d4+1 Large Monstrous Spiders, 1d3 Large Monstrous Scorpions, or a pack of 3d6 Medium Monstrous Spiders as a standard action. (If the base creature is not terrestrial, this power might summon other creatures of similar power.) These creatures arrive in 2d6 rounds and serve the vampire for up to 1 hour.
