Anaesthesia

A willing creature you touch falls unconscious for one hour, and cannot be woken by taking damage or any nonmagical means. While unconscious in this way, the creature loses access to all of its senses (sight, touch, hearing, taste and smell). The affected creature may take a short or long rest during the spell, provided that the length of the spell is equal to or longer than the duration of a short or long rest for that creature.

At Higher Levels. When you cast this spell from a spell slot of 2nd level or higher, the duration increases to 8 hours. When you cast this spell from a spell slot of 3rd level or higher, the duration increases to 12 hours. When you cast this spell from a spell slot of 4th level or higher, the duration increases by 12 hours for every spell slot level above 3rd.
