Your Wisdom score increases by 1.

As part of your action to Invoke Duplicity, if your duplicate is summoned into a region of dim light or darkness, you may cast a cantrip from your duplicate image as a free action. This cannot be used with any metamagic feat or other spell modifier.

As a bonus action, you can attempt to split your concentration by making a spellcasting check, DC15. You have advantage on this check if you are standing in dim light or darkness. If you succeed, you can concentrate on a second spell for 3 rounds while still maintaining concentration on your Invoke Duplicity. Once this spell is ended, you lose concentration on your Invoke Duplicity and cannot concentrate on another spell for 1 minute.
