Calamity Host[edit]

The Story of The Calamity and Birth of Calamity Catalyst[edit]

All records about the Calamity were purged by greater powers to prevent anyone from remembering the horrible acts of destruction the Great Wyrm of Calamity brought in his maddened rage upon all creation. The Great Wyrm was an ancient dragon whose power far surpassed anything else in the first eons after the multiverse was born. The fledgling gods' bickering and the pointless casualties of their wars caused this primordial beast to fall into a pit of bottomless madness and rage, in their grief over the loss of life it tore its fangs into the gods, causing untold destruction. After a harrowing victory against the Mad Wyrm was achieved, the beasts soul was torn into Five pieces that vanished into the winds of Ether. This wasn’t the end of the Wyrm, however, as its survival instincts made sure that the pieces would manifest as items of great power known as Calamity Catalysts. The biggest piece of its soul latched onto a mortal soul and thus came about the Host of Calamity’s birth. The story of the Hosts never had a happy ending, born to carry a great burden and gained fear from others who found out that the Beast still lurked among the worlds. The Will of Calamity made sure that the Host would always reincarnate, thus the Cycle of Calamity came to be, and would forever perpetuate until the day that the Beast of Calamity would be free once more, or the goal of its cycle broken.

Creating a Host of Calamity[edit]

Hosts of Calamity are mortal souls reborn again and again across all of space and time across the countless worlds of the multiverse. They are bound by Fate to manifest their power from the Ancient soul of the Wyrm inside of them. These Abyssal powers grant them many things, but the cost of using their powers is high, many times resulting in their early death. Not many remember or even know about the Wyrm, but those who do fear the Host, for there is the ever gnawing chance that the Wyrm would be freed by the Host and finish what it had started countless eons ago. The Host is forced to either stave off the Rage and madness of the mad Wyrm and find their own balance in the cycle, or risk bringing about total Annihilation and their own demise. Attention! To play this class you must ask your DM for permission, and you must play a human character.

Binding Seal[edit]

Starting at 1st level, you will be bound by a powerful, nearly unbreakable seal to make sure that there is at least one fail save against the Mad Wyrm. The Host must follow these rules:

  • One shall not ever talk about the Mad Wyrm himself, not to anyone.
  • Protect Life, but know when you must kill to protect.
  • Hold your head high, anything else is unjustly towards The Wyrms forgotten legacy.

If the Host breaks one of these seals they are attacked by a wave of crippling pain, gaining one level of exhaustion for a day. Breaking more within after one time doubles this pain. Lamenting for a day without breaking more tenets one can cure themselves of this exhaustion.

Abyssal Core[edit]

Starting at 1st level, you can activate the first piece of the Wyrm, the Calamity Core. This core resides within the soul of every Host of Calamity. It contains the dragon’s own soul and has a multitude of functions. The Core has the power to produce an abundant supply of power to the host at a constant, but controlled rate.

You gain 2 Abyssal Points at 1st level and gain 2 more each level after. During a short rest, you recover a number of spent Abyssal Points equal to your Constitution modifier (minimum 1). You recover all spent abyssal points upon completing a long rest.

Protective Field
