As Leomund's secure shelter (see page 247 of the Player's Handbook), except that the hidden lodge is perfectly camouflaged to blend in with whatever terrain or surroundings are appropriate.
It might appear as a house-sized boulder in a rocky or mountainous area, as a sand dune in the desert, as a densely tangled thicket, a grassy knoll, or even a mighty tree.
The hidden lodge also obscures all telltale signs of habitation, including any smoke, light, or sound coming from within.
At any distance of more than 30 feet, the lodge is indistinguishable from natural terrain.
Any creature approaching within 30 feet is entitled to a DC 30 Survival check to spot the hidden lodge as an artificial dwelling and not a natural part of the landscape.
Focus: The focus of an alarm spell (silver wire and a tiny bell), if this benefit is to be included in the hidden lodge (see the Leomund's secure shelter description for more information).
