You sever the connection between the weave and both creatures and items. Choose a point within range, then choose up to 6 targets within 15 feet of that point. Targets lose all magical effects currently affecting them, good or bad. 
If one of your targets is an item, you make an ability check using your spellcasting ability. The DC equals 15 plus one for each level of rarity of the item. Legendary Items and Artifacts are unaffected by this spell. If you succeed on the ability check, that item loses any magical properties for a number of days equal to 4 minus the level of rarity of the item (minimum of 1 day). For example, an uncommon magic item would lose its magical properties for 2 days, where as a rare item would lose them for one.
