Titan

This fighter has spent his time studying the arts of strength. These Titians are really strong and can control pure power at times. This power they consume in their bodies and make them unstoppable warriors. On the battlefield, they can single-handed wipe an entire army...of goblins. If you ever see a Titan charging at you, start saying your final words because your about to become nothing but dust. 

Titan Punch

Once you pick this subclass, your punches are now filled with the untamed power of the Titan. On a hit, your punch deals an additional 1d6 force damage. If this drops an enemy below 0HP it creates an explosion that all creatures within 5ft take 1d8 force damage.

Titans Charge

At 3rd Level, If you are holding a shield and no weapon and you use the dash option, all enemies in your path must succeed in a DEX Save or take 1d8 force damage and fall prone. The DEX save is equal to 8 + STR + Proficiency Bonus. Every 3 levels, your dash gains an additional 1d8 Force damage. 

Titans Wrath

At 7th Level, you can harness to power of the Titan to turn your body into pure energy. Punch through enemies as they're paper.

Once Per Long Rest:

All equipment disappears and you gain +3 AC,+50 Temporary HP, and +30 ft of movement. Your shield remains on you and like the rest of your body, it is consumed in the cosmic purple energy of the titan. All melee attacks deal 4d6 Force damage. Your shield deals 3d8 Force damage with a melee attack and for a Ranged attack, it is 30/50ft and deals 4d6 Force damage on a hit. This lasts for 1 Minute. Every Subclass level you deal an extra 1 die for each attack.

SLAM!

At 10th Level, if you fall more than 10ft you can slam down and everyone in a 35ft radius must succeed in a DEX save or take 6d6+3 Force damage. All creatures killed explode and all creatures within 5ft take 3d8 Force Damage.  You also take half of the fall damage.

Titans strength

At 15th Level, your titan energy has flower through your body and you now control it. Your speed increases by 30ft and your strength goes up 4.  Any final blow you deal, the creature blows up and all creatures within 5ft take 4d6 Force Damage.

Titan Armor

At 18th Level, your titan strength has become so strong that you can't wear armor. It is replaced with 20 total AC. When you take more than 10 damage, you can choose to take Half damage (Rounded Down) and lose 1 AC. At the end of the day, you regain 1d4 AC (to a maximum of 20). If you lose all 20 AC, you take 10d10 damage per round without any AC. You need a Wish Spell, Greater Restoration, or Armor of Sacrifice to stop the damage.
