Sharp Tongue

You are a master of combat, as well as insulting people. Your words are always hard-hitting, but your favourite mockeries are about your opponent's uselessness in combat. So, you've trained to weave some not so pleasant words between your attacks to distract your enemies. You get the following benefits:

• You learn Vicious Mockery cantrip, if you don't know one;
• On your turn, when you hit an enemy with a melee attack, you can as a bonus action cast Vicious Mockery cantrip on the enemy hit, insulting his bad fiighting style;
• If at least one attack was a critical hit, target makes its saving throw with disadvantage.
