Path of the Spiked Juggernaut

Battle-hardened warriors who turn their armor into a weapon, Iron Thorns wade into the thick of battle and dare their enemies to strike them. Every blow against them is answered with pain, while their brutal charges and intimidating presence force enemies to fight on their terms. Their bodies become weapons of war, covered in spikes and forged through years of relentless combat.

This subclass allows you to punish those how punish you and control the battle field.
