Detect Undead

For the duration, you can sense the presence and location of any undead, corpses and recently reanimated or revived bodies (up to 7 days from reanimation) within 60 feet of you. If you sense death or undeath, if any, this way, you see and smell an aura of rot emitting from them. Aside from the general size and shape, you are unable to identify anything else about the creature.

The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 6 feet of wood or dirt.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the range of the spell increases by 30 feet for each slot level above 5th.
