THIS is my worry. Any rest we take means we seriously lose the element of surprise. But our defenders are all kinds of beat up. Do we completely clear this level (and possibly the room above Deadeye's lair: the spiral staircase) and then set up some kind of watch/guard on the room leading down so we can take out anyone that ventures up? Viator only needs 4 hours anyway in which he is fully aware of his surroundings, so i could actual be on full watch whilst others get their 6 hours sleep in rota.
Just my 2p
Sounds like a vote for tacks A and B (see my post above). Clearing out this level and setting up defenses for the level below as we sleep. Sounds good to me. Anyone else have any input?
