Whisp reapplies Non-detection to everyone for 8 hours and wishes you good fortune.
Haywire up-casts Aid giving everyone +15 max and current HP for 8 hours (remember that when you heal, you keep the higher max)
Qhu casts Darkvision for anyone that needs it, to save Warhol some spell slots.

The dry tunnels give way to a tiny stream of noxious bubbling liquid that smells of rot and ammonia. The steam becomes small pools that must be carefully avoided.
Marvin halts the group. Ahead he hears the sounds of.... digging and falling water. Marvin just catches a flicker of movement low to the ground and beyond the range of his Darkvision towards the top of the map.
if there is anything else you want to do during the first 3 hours, feel free to post that as well as your current actions?
