When this wooden pole is driven into the ground with a hearty and word-perfect rendition of The Treant Song of Tenting*, a spacious and comfortable temporary dwelling forms itself around it. Roll a CHA (performance) check. The result is the number of medium creatures that will be admitted into the tent (which will swell to accommodate them roomily).The inside of the tent will always feel like a temperate forest in early autumn, regardless of the weather outside it.

The dwelling itself is invisible, but will draw natural elements from the surrounding terrain to cover itself with (e.g. leaves, moss, soil, dust, etc). Ability checks to see the tent are rolled at a disadvantage and the tent is immune to all forms of damage.

The invisible force constructing the tent also restricts entry to it. No creature can enter while armed with weapons, magical items, or spells that do slashing or fire damage. Forest creatures are however drawn powerfully to the tent and can cross the boundary without resistance.

*TREANT SONG OF TENTING

A hacking slashing fiery thing, I shall never be / a friend a friend I am indeed to each and every tree.

The bark and moss I hold them dear, and all green things that grow / The trees from root to twiggy leaf, a love I only know.

A hacking slashing burning thing, O! I shall never be / a friend a friend I am indeed to each and every tree.

Unsheathe your swords, throw down your axe, lay them upon the ground / or you shall never cross this hearth, by leap and nor by bound.

A hacking slashing blazing thing, O! I shall never be / A friend a friend I am indeed to each and every tree.
