Malicious

You take sick pleasure in the unnerving of others, and rejoice whenever you are given the opportunity to inflict pain.

• You gain proficiency in charisma (intimidation), if you already have proficiency with it you gain Expertise instead.
• You can use your Bonus Action to strike fear into the heart of a chosen victim. Make an Intimidation check against one creature that can see you, that creature must make a Wisdom saving throw versus your Intimidation roll. On a fail they become frightened of you for 1 minute or until you do not attack them for 2 turns and while frightened in this way your proficiency bonus is doubled on attacks against the frightened target. You may only have one target frightened in this way at a time.
• Whenever you critically hit a creature with a weapon attack you may choose to hinder them in one of the following ways: Gouge out their eyes rendering them blind in one (giving them disadvantage on Perception checks) or both (blinding them completely). Horrifically scar their face giving them disadvantage on Charisma checks. Cripple a limb or if the damage would kill them it is hacked off, if aimed at a leg their speed is halved; if aimed at an arm they lose functionality of the hand. 

All effects of the "Hindering" ability of your critical hits are permanent unless regenerate is cast on the wound.
