Bottled Space

You can enlarge the interior of a specific target object, like a closed vehicle (e.g., a carriage) or a tent, temporarily. The inside feels consistently warm and dry, unaffected by external conditions. The internal space can expand up to five times its initial size, but the outer appearance remains unchanged. Only when viewed through a window into the space, the expanded interior becomes visible to an observer.

The object emits a subtle magical aura recognizable by spells like Detect Magic and Identify. If anything or anyone inside exceeds the object’s initial size capacity, it will be safely expelled to an adjacent unoccupied space once the spell concludes or if the object is destroyed.

Casting this as a ritual extends its duration to 24 hours.

To make the enlargement permanent, maintain the enchantment on the object for a continuous month. The object will then possess arcane properties, becoming magical and immune to further effects of this spell.
