Titanspawn are titanic terrors of immense size and strength that live only to destroy. The most powerful Titanspawn is the Tarrasque, whose legend spread across countless worlds.

All Titanspawn can sleep for centuries and do not need to eat, drink, or even breathe while hibernating. While hibernating, a Titanspawn’s resistances double in value.

It cannot be located by divination effects, and for any saving throw, it uses the outcome for one degree of success better than the result.

Titanspawn have regeneration powerful enough to revive them even if slain by a death effect. If the Titanspawn fails a save against an effect that would kill it instantly, it rises from death 3 rounds later with 1 Hit Point. It can be banished, imprisoned, or transported away as a means to save a region, or kept in a state of dying by an effect that deals constant damage. A complex and expensive ritual culminating in a word that douses the Titanspawn’s flames can be used to deactivate its regeneration, but no method of deactivating Tarrasque’s regeneration has yet been discovered.

Destructive Frenzy [three-actions] The Tarrasque makes a jaws Strike, two claw Strikes, two horn Strikes, and one tail Strike in any order.

Fast Swallow [reaction] Trigger The Tarrasque Grabs a creature with its jaws; Effect The Tarrasque uses Swallow Whole.
