I was about to ask if you were keeping the marching order but, as people posted, I can see that Stratus, Anson and Caer (and presumably, Havoc moved in first.
I'm not sure who has darkvision and how far it goes but only Caer and Havoc saw the zombies hiding. But not before Stratus and Anson went in ahead. (I used Passive Perception)
The zombies get to go before everyone who failed. I will let Caer and Havoc post before the zombies go.
I think that it's fair that Caer's Druidcraft reduces Anson's lighting time by 1 round. It's helping the embers/coals light up, but it's a magical brazier, right? So the ritual sticks need to be involved to please the gods.
I like this. It removes the +1 from the d3+1 and it uses an action. Let it be so!
