I'm a druid/wizard and our party is trying to do some underwater spelunking. I cast the Water Breathing ritual, so we can all breathe underwater for 24 hours. After a few hours of adventuring we've been beat up pretty badly, so I proposed that we rest in Leomund's Tiny Hut. Since it lasts for 8 hours, we would be able to be protected for the duration of a long rest. The question remains, though: what happens underwater with Tiny Hut? The only real guidance comes from this line:
The atmosphere inside the space is comfortable and dry, regardless of the weather outside.
Would the hut empty itself of water? If it stayed water-logged, would we still be able to complete a long rest, since we could breathe?
Best Answer
Being underwater does not prevent long-resting
There are no explicit rules which prevent or impede resting whilst underwater, so you would still be able to rest if the hut was waterlogged.
For what its' worth, the hut will not be waterlogged. It will be
as stated in the spell description. The additional clause 'regardless of the weather outside' describes the effect in more detail, but does not restrict the the effect to weather-protection. The hut's interior is comfortable and dry, even whilst underwater.
