Leomund's secure shelter

Leomund's secure shelter is a conjuration spell that creates a sturdy cottage. It was presumably developed by Leomund.

Effect
You conjure a sturdy cottage or lodge made of material that is common in the area where the spell is cast - stone, timber, or (at worst) sod. The floor is level, clean, and dry. In all respects the lodging resembles a normal cottage, with a sturdy door, two shuttered windows, and a small fireplace.

The shelter has no heating or cooling source (other than natural insulation qualities). Therefore, it must be heated as a normal dwelling, and extreme heat adversely affects it and its occupants. The dwelling does, however, provide considerable security otherwise - it is as strong as a normal stone building, regardless of its actual material composition. The dwelling resists flames and fire as if it were stone. It is impervious to normal missiles (but not the sort cast by siege machinery or giants).

The door, shutters, and even chimney are secure against intrusion, the former two being arcane locked and the latter secured by an iron grate at the top and a narrow flue. In addition, these three areas are protected by an alarm spell. Finally, an unseen servant is conjured to provide service to you for the duration of the shelter.

The secure shelter contains crude furnishings - eight bunks, a trestle table, eight stools, and a writing desk.

Material components
A square chip of stone, crushed lime, a few grains of sand, a sprinkling of water, and several splinters of wood. These must be augmented by the components of the alarm spell (string and a bit of wood) and the focus of the alarm spell (silver wire and a tiny bell) if these benefits are to be included.
