Usable by any class 

Due to the  battle pressure you exude even out of combat if someone or something looks you in the eyes you gain a permanent +2 to all rolls against them. Once you make eye contact they need to roll an intimidation check of a 16DC plus your proficiency bonus, on a  failed save if you touch them in any way before they either leave or hit you first you gain another permanent 6AC against only that target due to them convincing themselves mentally that they couldnt scratch you if they tried. This affect is only negated if the target dies or touches you first directly after making eye contact. They are not aware of either affects.

If an enemy beats the 16DC plus your proficiency bonus they are immune to the 2nd effect permanently from only your character.
