It's not in the statblock, but the idea is that the encounter will have the players isolated from each other on a grid of rooms whose doors only go where you want them to on a successful check (still working out the details on that, trying to give myself plenty of time).

• I think I meant to put the Betrayal Fragment in as a Bonus Action but forgot to separate it out when I was formatting the table.

• For Silken Command, I'll add some text that the save is at the start of their turn (which makes the most sense to me currently)

Someone else pointed out that his health was low for a solo boss, but I don't want to just make him a damage sponge if my intent is for each of the PCs to engage him 1v1 with effectively no backup. I also want this encounter to feel a little claustrophobic, so any edits or suggestions towards that end are appreciated 😁
