Detect Weave

For the duration, you sense the condition of the weave within 30 feet of you. If you sense the weave in this way, you can determine how likely it is that other magical spells will work as intended (guaranteed, very likely, probably likely, probably unlikely, very unlikely, not at all).

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 3 feet of wood or dirt.
