Colossal Damage. Bludgeoning, piercing, and slashing daamge inflicted by the regisaur is magical for the purposed of overcoming resistances and immunity. In addition, the regisaur deals double damage to objects, structures, and targets of Huge size or greater.
Colossal Movement. When the regisaur moves it can enter the space of Large or smaller creatures. The first time it enters a creature's space it can make a stomp attack against the creature. The regisaur can make one stomp attack for each 40 feet it moves.
Colossal Parts. The regisaur has five parts as indicated below. Each part can be targeted separately and has its own pool of hit points.
- Head. 330 (20d20 + 120) hit points. When the head is reduced to 0 hit points the regisaur is unconscious for 1 minute after which it regains 50 hit points and is no longer unconscious.
- Torso. 825 (50d20 + 300) hit points. When the torso is reduced to 0 hit points the regisaur dies.
- Leg (2). 165 (10d20 + 60) hit points each. When a leg is reduced to 0 hit points the regisaur's speed is reduced in half and it has disadvantage on its stomp attacks. When both legs are reduced to 0 hit points the regisaur falls prone and it cannot make stomp attacks.
- Tail. 495 (30d20 + 180) hit points. When the tail is reduced to 0 hit points the regisaur has disadvantage on Dexterity checks and saves and it can no longer make tail attacks.
Colossal Size. The regisaur's space is 80 feet by 80 feet. Attacks with a reach or range of less than 20 feet must be made from within the regisaur's space and can only target or effect the regisuars legs (see colossal parts). Additionally, when the regisaur hits with a Large or smaller target with a melee attack, any creature adjacent to the initial target must make a DC 25 Dexterity saving throw or suffer the same effects as the initial target.
Keen Smell. The regisaur has advantage on Wisdom (Perception) checks that rely on smell.
Magic Resistance. The regisaur has advantage on saving throws against spells and other magical effects.
Multiattack. The regisaur makes one Bite, Fling, or Stomp attack and one Tail attack. The regisaur can't target the same creature with both attacks and only one target can be a Large or smaller Creature.
Bite. Melee Weapon Attack: +17 to hit, reach 40 ft., one target. Hit: 138 (20d12 + 8) piercing damage, and the target has the grappled condition (escape DC 18). Until this grapple ends, the target has the restrained condition, and the regisaur can't Bite another target.
Fling. One Huge or smaller object held or creature grappled by the regisaur is thrown up to 120 feet in a random direction and knocked prone. If a thrown target strikes a solid surface, the target takes 50 (12d6 + 8) bludgeoning damage. If the target is thrown at another creature, that creature must succeed on a DC 25 Dexterity saving throw or take the same damage and be knocked prone.
Stomp. Melee Weapon Attack: +17 to hit, reach 5 ft., one Large or larger target or all targets within 10 feet of a Medium target. Hit: 94 (16d10 + 8) slashing damage, and the target has the grappled condition (escape DC 18). Until this grapple ends, the target has the restrained condition, and the regisaur can't Bite another target.
Tail. Melee Weapon Attack: +17 to hit, reach 120 ft., one target. Hit: 98 (20d8 + 8) bludgeoning damage and the target must make a DC ?? Strength saving throw or be pushed 60 feet and knocked prone.
Swallow. Melee Weapon Attack: +17 to hit, reach 5 ft., one Huge or smaller creature grappled by the regisaur. Hit: The regisaur swallows the target, and the grapple ends. A swallowed creature has the blinded and restrained conditions, it has total cover against attacks and other effects outside the regisaur, and it takes 35 (10d6) acid damage at the start of each of its turns. The regisaur can have up to two Huge creatures swallowed at a time.
If the regisaur takes 50 damage or more on a single turn from swallowed creatures, the regisaur must succeed on a DC 16 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall in a space within 20 feet of the regisaur and have the prone condition; the creatures no longer have the blinded and restrained conditions.
Crush. When the regisaur is knocked prone, all creatures in its space must make a DC 25 Dexterity saving throw, taking 118 (20d10 + 8) bludgeoning damage and be knocked prone and restrained on failed save, or half as much damage and pushed to an unoccupuied space adjacent to the regisaur on a success. While restrained in this way, the creature (or another creature within 5 feet of it) can use its action to make a DC 26 Strength check. On a success, the creature relocates to an unoccupied space of its choice within 5 feet of the colossus and is no longer restrained.
Shake. Immediately after the regisaur takes damage from a creature riding or climbing it, it attempts to shake the creature off. Each creature on the regisaur must succeed on a DC 25 Strength saving throw, or be thrown 60 feet, taking 29 (6d6 + 8) bludgeoning damage and it has the prone condition when it lands.
