Components: S, M

Materials: a pouch of partially decayed food

Duration: Concentration, up to 10 minutes

A thin network of near-invisible fungus mycelia spreads over each solid surface in a 20-foot radius sphere, centered on a point of your choice you can see within range. The sphere spreads around corners. Until the spell ends, you are alerted when a Size Tiny or larger creature touches the surface of the mycelia. The alert awakens you if you are sleeping. You learn the creature’s size, how many legs it has, and if it is wearing or carrying metal. The mycelia are invisible to creatures unless they succeed on an Intelligence (Investigation) ability check against your spell save DC, or its passive Intelligence (Investigation) skill is higher than your spell save DC. It has advantage on this check if it saw you cast the spell.

At higher levels: When you cast this spell using a spell slot of 4th or 5th level, you can maintain your concentration on the spell for up to 8 hours. When you use a spell slot of 6th level or higher, you can maintain your concentration on the spell for up to 24 hours.
