Unravelling Weave

When you cast this spell, you create a sphere of up to 30 feet in radius centred on a point within range, where magical laws begin to break down. Any creature that casts a spell or uses a magic item in this area must roll a d10. On 1, the spell or magic item fails, expending any spell slots or charges without effect.

At Higher Levels. When you cast this spell at 2nd level or higher, the DC for magical failure increases by 1 for each slot level above 1st.
