Tutt's Tiny Tent

You conjure a magical dome that provides shelter for up to 9 Medium creatures, maintaining a comfortable, dry interior while blocking lights, sounds, and smells from exiting. From the inside, the caster can adjust the transparency, allowing occupants to observe their surroundings without being seen. The caster can also choose to make the tent visible from the outside, appearing as a simple or elaborate tent no larger than its interior capacity. It may resemble anything from a single sleeping tent to a luxurious travel pavilion. The tent has 100 hit points, is immune to nonmagical damage, and has an AC of 10 + your spellcasting ability modifier. Magical attacks can target the tent, and every 20 points of damage dealt require a Constitution saving throw (DC 10 or half the damage taken, whichever is higher) to maintain concentration; failure causes the tent to collapse, harmlessly expelling occupants to adjacent spaces. It blends seamlessly into its surroundings when invisible, shields against weather, and prevents creatures from passing through its walls. The caster can dismiss it early as a free action. When cast with a spell slot of 4th level or higher, the tent gains 20 additional hit points per slot level above 3rd.
