Witch’s Grace
The power of your sympathy and empathy can overwhelm the hardest of hearts, making you a powerful force for reconciliation. When a creature that you and your allies haven’t harmed or insulted deals damage to you or an ally of yours that you can see or hear, or forces you or an ally you can see or hear to make a saving throw, you can use an action on your turn to implore the creature to cease hostility.
At the start of your next turn, if the creature has not been attacked, damaged, or verbally threatened by you and your allies since you used this feature, it feels the presence of a curse eager to inflict consequences if it harms you or your allies. For the next 24 hours, or until you or your allies attack, threaten, or force the creature to make a saving throw, the act of harming you or your allies causes the curse to immediately take effect. While cursed in this way, the creature has Disadvantage on D20 Tests for 24 hours, including on the action that triggered the curse.
Creatures that can’t understand a language can’t be affected by this feature. If you or your allies have harmed or insulted a creature but made sufficient amends (as determined by the GM), you can use this feature as if you have not done harm or given insult.
Once you use this feature, you can’t do so again until you finish a Long Rest. You can also restore your use of it by expending a level 7+ spell slot (no action required).
