Path of the Howitzer

You are not just a weapon. You are the weapon. Wielding the power of high explosives and adrenaline, you blast your way through the battlefield at a catastrophic speed. 

Wrist-Cannons

Starting at 3rd level, your unarmed strikes have become explosive. Using wrist mounted firearms you enhance your unarmed strikes while raging. You gain the following benefits.

• You gain proficiency in firearms.
• While raging, you can roll a d10 in place of the normal damage of your unarmed strike. 
• You can make a ranged attack using your unarmed strikes (range 30/60). 

Wild Abandon

At 6th level, you take advantage of leaving an opening in your defenses. When you use Reckless Attack while raging, you gain a bonus to your speed equal to 5 times your proficiency bonus, and you can make one attack as a bonus action. These bonuses last until the beginning of your next turn. 

You can use this feature a number of times equal to your proficiency bonus each long rest. 

Defensive Countermeasures

At 10th level, you have learned how to enhance your defenses with explosives. You gain the ability to cast glyph of warding targeting yourself or a suit of armor. You do not need material components and Constitution is your spellcasting ability for this spell. You, or the person wearing the armor with the glyph on it, do not take damage from the spell when it is triggered. You can only have one glyph active at a time. 

After you cast this spell, you can’t use this feature again until you complete a long rest. 

Keep ‘em Close

At 14th level, you learn how to manipulate the battlefield to your benefit. While raging, you can grapple a creature you hit with your unarmed strikes. While you have a creature grappled, you have advantage on attack rolls against that creature, and any attack that hits is treated as a critical hit.
