Dungeons & Dragons 5e Element 133 Class Feature: Heavy Tank

Your intense training and sheer will have caused your muscles and bone structure to alter. You can roll a d4 and add the result to your normal unarmed damage and your carrying capacity is doubled.

Additionally, nothing can stand in between you and your enemies. Your movement is unaffected by difficult terrain, and you can push enemies out of your way, being able to shove as a bonus action. Your movement speed is not reduced when climbing or swimming, and your standing long jump and high jump distance is equal to your running long jump and high distance.

Finally, your resilience can keep you moving despite heavy damage. If you drop to 0 hit points and don't die outright, you can make a DC 10 Constitution saving throw. If you succeed, you drop to 1 hit point instead. Each time you use this feature after the first, the DC increases by 5. When you finish a long rest this resets the DC to 10.
