Herrscher of Chaos

The Herrscher of Chaos combines the power of frost and fire and fuses those totally contrary parts into one with the power of gravitation. Thus an unstable and deadly combination came to earth and let the enemies of the Herrscher tremble in fear.

Burning Will and Freezing Soul

Blazing Blade and cold sword

Starting with level 3, You can once per battle either "infuse" a greatsword with fire or ice. Each Weapon can only be infused three times per battle and if you dont attack with a weapon after you infused it the infusion stops. If you did so your sword now either deals 2d8 additional fire damage or 2d6 additional cold damage per hit, if wielded with a two handed weapon. Each damage rises to 3d6 at level 8, 4d6 at level 11, 5d6 at level 15 and 6d6 at level 18.

Spreading Chaos

Starting at level 5, each time you hit a creature or object with an infused weapon, you mark the enemy with either "over heating" if it was fire infused or "absolute zero" if it was ice infused. If infused with "absolute zero" the creature is forced to make a constitution saving throw on every Action he does. If it succeeds the saving throw nothing happens. If it don't succeeds it is frozen until next turn. The Action is stopped and until it's next turn it automatically loses every saving throw it would have to make.

Melting Ice: When a creature attached with absolute zero is attacked with a fire infused weapon it takes an additional 2d6 fire damage. This additional damage rises to 3d6 at level 8 and after that by 1d6 every 2 level.

If infused with "over heating" the creature is forced to make a constitution saving throw on every Action he does. If it succeeds the saving throw nothing happens. If it don't succeeds it is burning until next turn. The creature will take 1d4 fire damage with every saving throw it has to make and every time it is attacked. This rises to 1d6 when reaching level 10, to 1d8 when reaching level 15 and to 1d12 when reaching level 20.

Freezing Flame: When a creature attached with over heating is attacked with a ice infused weapon it takes an additional 2d6 ice damage. This additional damage rises to 3d6 at level 10 and after that by 1d6 every 4 level and at level 20 it will deal 7d6.

Once per turn only one Melting Ice or Freezing Flame can be triggered.

You can only infuse a two handed weapon.

Field of Entropy

Starting at level 7 you can once per battle make every non friendly creature in a 15 foot radius has to make a strength saving throw. If they succeed they get one "exhaustion" counter. For every exhaustion counter the save DC the specific mob has to do for against "field of Entropy" rises by 1. When a creature doesn't succeeds the saving throw its speed now is halved and it loses its bonus action both for 2 turn. Every time a creature doesn't succeed the saving throw they get an "anti entropy" counter. For every anti entropy counter the save DC for this creature sinks by 1. With the levels 10,  14, 17 and 20 you get one more usage of "Field of Entropy"

Event Horizon

Starting from level 10, you can choose any creature of any height in a 100 feet range. It gets pulled right in front of you. It can't use a reaction to this action. After it is Infront of you, a black hole with a 10 feet radius is created. Nothing can leave this. While in this black hole first you than the enemy have your turns. Each of you does 3 turns and then you leave the black hole. While the black hole exists every creature outside of it is not moving. The time only flows in the black hole. This state ends with the end of the 3rd turn too.

Bursting Black hole

Starting at level 15, you can destroy your black hole. If you do so, the creature takes as much damage as it has hp left. Then you take half the damage the creature took. If you die through this, neither you nor the other creature can be revived and your body and the enemies once will disappear and the inventory and equipment with it.

A Herrschers Legacy

Starting at level 18 you gain a plus 2 on every damage roll you do inside your black hole against humans. You also gain 2 strength and 2 Constitution.
