Cataclysmic Force[edit]

An army prepares for battle against the neighboring kingdom's forces. They enter formation and shout battle cries, steeling themselves for whatever the foe may bring. However, only one man steps forward against this army. In their confusion, he devastates their ranks, leaving none alive. As he proceeds back to his king, he laments that it was all too easy.

Unstoppable Warriors[edit]

Cataclysmic forces, often referred to as cataclysms, are fearsome fighters whose ability to utterly annihilate their opposition in an instant is feared by even famed mercenaries. Any who would attempt to face one of these warriors is unlikely to leave in one piece, but to be on the same side as a cataclysm is victory assured.

Creating a Cataclysmic Force[edit]

When creating a cataclysm, ponder how you obtained such power, and why you use it. Have you spent your years training your already powerful body, or were you perhaps gifted power from an ascendant being? Do you wield this power against those who would challenge your freedom, or do you raise your weapon against the malevolent, showing no mercy in retribution for their actions? Your beliefs are the only thing standing between you and the lives of others, a fact that can easily mold you into a conqueror of innocents, or a protector of innocents.

If you are using a weapon that already has a bonus to attack or damage rolls, you apply the higher bonus. Also your slashing weapons deal double damage against objects and structures.

Furthermore, your critical hits with weapon attacks ignore all resistances, and you treat immunities as resistances.

Superlative Strength[edit]

Your sheer strength is unmatched by even the most experienced soldiers. At 20th level, your Strength score increases by 6 and your maximum Strength score becomes 26.

The wall is opaque and lasts for 1 minute.When the wall is created, each creature within the area must make a Dexterity saving throw or take 2d10 fire damage and 1d10 necrotic damage, or half as much on a successful save. They are also pushed forward 10 feet into the ring or backward 10 feet out of the ring, your choice. A creature who ends their turn inside the wall takes 1d10 fire damage and 1d6 necrotic damage and is pushed 10 feet into the ring. A creature takes the same damage and push when they enter the wall for the first time on a turn or end their turn there. The fire does not cast heat, nor does it ignite flammable objects.
