Wow! You cast Zone Of Truth for 567th time! Now here comes your reward.... 

You've cast Zone Of Truth so many times that you've learned to adapt it to anything that's magical. Three times per day, you can imbue Zone Of Truth with any spell or magic item property (Only one) and create a zone of it. Subtract one damage die (If applicable, To a minimum of one.) and change the spell's dimensions to a 20x20ft radius sphere. The zone uses what the spell normally does, but in a zone. Therefore, casting lightning bolt with this feat would cast Zone Of Lightning Bolt, which would do 7D6 lightning damage to any creature who enters the sphere or ends their turn their, on the normal saving throw and other rules. To determine the spell slot level, add the spell slot level plus 4 and subtract 1D4. The only spell you can not channel into a Zone is a Wish spell. Unless, of course, you are granted to do so with a wish. If you cast any spell that already has the dimensions of a sphere, then impose disadvantage on any rolls OR add one damage die (If applicable)
