Befuddle

You attempt to magically distract a creature in the process of maintaining concentration, on a spell of 2nd level or lower. Target creature must make a WIS save vs your Spell DC.  If they fail, their concentration is broken and they can not cast another concentration spell for 1 min.  On a success, they resist and and are immune to Befuddle for 1 min. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, concentration can be broken if its level is less than or equal to the level of the spell slot you used.
