Trial of the Sekhamas - "Cannot be damaged in next room" not working properly

Hey. Here to report a bug. In the trial of the sekhemas, I got super lucky on my merchant in the room just before the floor 4 boss, she sold me the boon of "Cannot take damage in the next room." The next room was the final boss of floor 4.

I thought I was home free and could just stand there and blast, but some of his attacks still managed to deal damage to me. I didn't take any honor damage, and the life damage I did take seemed reduced. However, it seems like the projectiles and the adds were able to deal life damage to me still. (And for context, I am mind over matter with eldritch battery.) The damage didn't seem to hit my mana at all, which is kind of weird.

I did manage to kill him, but the boon of not taking damage didn't completely work.

tl;dr - The floor 4 boss in trial of the sekhemas, his projectiles and the things that seem to spawn from the room can still damage you while you have the boon of "cannot take damage in the next room." Is it because the projectiles the room spawns aren't considered "his" or "by a monster?"

Same thing just happened to me on trying to get my time lost diamond. Thought I had an easy win on last boss with the boon and it didn’t work and I died. Very disappointing

Entered Room with the boon, as soon as Z. started to spin and used his lightning skills I was killed.

lost my run on a "against the darkness" jewel, super cool

Just happened the same thing. Seems like the boomerang one and the lightning dealing the damage.
