Determination, the air that good men breathe. I will kneel to failure not because it may be an enemy in victory, but rather in honor of the greatest teacher. I will accept my failures and turn them into weapons. You cannot consume my mind. I will remain awake against the nightmares I face. Put me through the Darkness and I will only come out a better person.

"Fools think they are the wise and preach it... But those who are Wise know they are fools and learn from it" -Theon, hermit in the Petal-thorn Mountains

Once per long rest you can become "Determined" and gain multiple effects (this feat stacks with other"Will of" feats)
For 6 hours you cannot be charmed and you are immune to psychic damage. You also cannot be surprised by attacks targeted on you. You also gain advantage on Wisdom checks and saves. If you already have advantage on Wisdom checks and saves without this feat, then you can double your wisdom modifier instead. After the 6 hour duration you get disadvantage on all WIsdom checks and saves. This remains until you take a long rest.
