Cannondwarf

You’ve developed the skills necessary to use your unique dwarven physique to launch yourself into enemy lines in order to cause maximum disruption and havoc.

• You can use your action to launch yourself at an enemy like a cannonball. To do so, you must have at least a 15ft running start. The target and all creatures within 5 feet of the target must succeed on a DEX saving throw equal to 8 + STR modifier + proficiency bonus or the affected enemies are knocked prone. In addition, affected enemies take your Brutish Attack damage roll(s) with no modifiers. 
• You gain temporary hit points equal to the damage that you dealt using this skill until the end of your next turn.
