Daily Punch 8-14-17 Twist the Mental Knife feat for DnD 5e

Let’s get a few of my more recent ideas out there. Here is one for DnD 5e.

Twist the Mental Knife

When it comes to cutting people, you like to do it on a different level. Gain the following benefits:

• Increase your Wisdom to a maximum of 20.
• When you do psychic damage, add your Wisdom modifier to the damage amount.
