Tyrant

Ruling through fear and cruelty, Tyrants fight with malevolence and hate. Their unyielding stature makes them forces to be reckoned with on the field of battle.

Precedent

When you reduce a creature within your reach to zero hit points you can use a bonus action to attempt to terrify one of it's allies you can see within 30 feet of you.

The target must roll a Wisdom Saving Throw against your Intimidation skill + 8 or be frightened of you for 1 minute. At the end of each of its turns it can repeat the saving throw ending the effect on itself with a success.

you gain proficiency in intimidation if you do not have it already.

Stockpile

Before you roll to hit with an attack you can choose to forgo any number of attacks from your extra attack feature to attempt a stockpiled attack. For each attack you forgo, roll an additional instance of the weapons damage dice. If this attack is a critical hit, triple the number of damage dice instead of doubling it.

Iron Fist

You have advantage on melee attack rolls against creatures that have the frightened condition. 

Brutal Blows

Your attacks tend to hit hard. Before you roll a melee weapon attack you can choose to take a -10 penalty to the roll, if you hit you deal damage as if you had rolled the maximum possible number on the weapons damage dice. You can use this feature a number of times equal to your proficiency bonus.

Malevolent Ire

When a creature you can see within 30 feet of you hits with an attack against you or an ally you can use your reaction to force it to make a wisdom saving throw against your Intimidation + 8. On a failed save the creature is frightened of you for 1 minute. At the end of each of its turns it can repeat the saving throw ending the effect on itself with a success.
