Path of the Siege Tower (5e Subclass)
From D&D Wiki
The Embodiment of War
This subclass belongs to those barbarians who have really hardened their resolve; who rebel against traditions and who surpass the limits of those that have come before them. Whether with purpose or not, these warriors draw the majority of the battlefront's attention to themselves. They rage into the thick of a fight, take hits head on and drive through like a siege weapon. They shake off the mightiest of blows and their leather-like skin glances the sharpest of blades away from their beating heart and burning spirit. They don't bother to move out of the way other than from what they can only see as a distraction. They take up arms and bring the might of their stronghold's castle with them. They Fight. They Protect.
Beginning at 3rd level, your resolve is steeled to withstand even the most dangerous attack. While raging you have the option to make a Constitution saving throw in place of a Dexterity saving throw against effects that would not kill you outright, achieving the same effects as a Dexterity save through sheer grit.
Starting at 6th level, you have advantage on Dexterity saving throws against siege weapon attacks you can see. You still have advantage if you make a Constitution save through the use of the Unwavering feature. In addition, when you are subjected to a ranged attack that allows you to make a saving throw to only take half damage, you can instead use your reaction to take no damage if you succeed on the saving throw. You have advantage on Strength checks made to push, pull, lift, or break objects, doors, walls, or similar barriers.
At 10th level, you are no longer just a representation of your stronghold's might. You are the living metaphor! Once during your rage as an bonus action, you can channel your spirit to enlarge your body to suit it's size.
- Enlarge: Your size doubles in all dimensions, and your weight is multiplied by eight. This growth increases your size by one category - from Medium to Large, for example. If there isn't enough room for you to double in size, you attain the maximum possible size in the space available. Until the effect ends, you also has advantage on Strength Checks and Strength saving throws. Your Weapons also grow to match your new size unless they are otherwise already accommodating. While these Weapons are enlarged, your Attacks with them deal 1d4 extra damage.
This effect lasts for the duration of the rage. If anything were to cancel this effect early, you cannot use this feature again until your next rage. Additionally, you can only use this feature a number of times equal to your Constitution modifier before needing a long rest to restore it's uses.
Starting at 14th level, your body now embodies your will as your rage is released. While raging, you are immune to slashing, bludgeoning, and piercing damage from non-magical weapons. At 18th level, you also gain resistance to magical slashing, bludgeoning, and piercing damage while raging.
