Dungeons & Dragons 2024 (D&D) Subclass: Circle of Entropy

Level 3: Catastrophic Power

You have mastered talents, both magical and martial, in your pursuit of the inevitable destruction of mortals and their works. When you finish a Short or Long Rest, you gain one of the following benefits until you finish your next Short or Long Rest.

Elemental Cataclysm. As a Magic action, you can expend a spell slot to cause elemental energy to burst in a 10-foot-radius Sphere centered on a point within 60 feet of yourself. Choose a damage type: Acid, Cold, Fire, or Lightning.

Each creature in the Sphere must make a Dexterity saving throw against your spell save DC. On a failed save, a creature takes 1d6 damage of the chosen type per level of the spell slot expended, and then has Vulnerability to that damage type for 1 minute. On a successful save, a creature takes half as much damage only. The target repeats the save at the end of each of its turns, ending the Vulnerability on a success.

Ruinous Smite. Once per turn when you deal damage with an attack with a weapon or an Unarmed Strike, you can choose to expend a spell slot to deal an extra 1d8 Necrotic damage, plus another 1d8 per level of the spell slot.

Weapon Mastery. Your supernatural connection to destruction allows you to use the mastery property of one kind of weapon of your choice with which you have proficiency, such as Shortbows or Quarterstaffs.

Whenever you finish a Long Rest, you can change the kind of weapon you choose. For example, you could switch to using the mastery property of Slings or Greatclubs.

Level 3: Ruin Incarnate

As a Bonus Action, you can expend a use of your Wild Shape to adopt an aspect of entropy and the inevitable end of all things for 10 minutes. You gain the following benefits.

All Things Pass. You have Advantage on attack rolls against Bloodied creatures.

Ironskin Armor. Your base AC becomes 14 plus your Wisdom modifier (minimum of +1) if your AC is lower than that.

Level 6: Many Roads to Ruin

Your mystic connection to catastrophe and destruction grows stronger. You gain the following benefits.

Elemental Assault. While your Ruin Incarnate feature is active, whenever you hit with a weapon or an Unarmed Strike, you can cause it to deal your choice of Acid, Cold, Fire, Lightning, or Necrotic damage rather than its normal damage type.

Increased Might. While your Ruin Incarnate feature is active, you can add your Wisdom modifier (minimum bonus of +1) to your Strength and Dexterity saving throws.

Inexorable Onslaught. You can attack twice instead of once whenever you take the Attack action on your turn.

Level 10: Shake the Earth

As a Magic action, you can strike the earth with a thunderous tremor and grow. When you do so, your size increases by one category (from Medium to Large, for example) for 10 minutes. In addition, each creature in a 30-foot Emanation originating from your new form must make a Dexterity saving throw against your spell save DC or have the Prone condition. The tremor deals Bludgeoning damage to each structure in contact with the ground in the area. To determine this damage, roll a number of d10s equal to your Druid level, and add them together.

While your size is increased by this feature, your attacks with weapons and Unarmed Strikes deal an extra 1d4 damage on a hit.

Once you use this feature, you can’t use it again until you finish a Long Rest.

Level 14: Entropy's Apex

You have mastered the ability to hasten the inevitable slide toward entropy. You gain the following benefits.

Enhanced Ruinous Smite. Until the end of your next turn, any creature affected by your Ruinous Smite suffers a Critical Hit on a roll of 19-20 on the d20.

Improved Inexorable Onslaught. While your Ruin Incarnate feature is active, you can attack with a weapon or an Unarmed Strike three times instead of once whenever you take the Attack action on your turn.

World Breaker. You regain your use of your Shake the Earth feature when you finish a Short or Long Rest.
