Amorphic. The Krasis is able to change shape in order to fit through spaces 1 inch thick at smallest. The Krasis always changes shape to fit into its surroundings. There are 3 specific amorphic forms available to the Krasis that affect its AC and max HP. All HP loss is carried over from the previous amorphic shape, even if this would result in the death of a Krasis.
TINY (mouse-sized) - Max HP: 30, AC: 19. When tiny, the Krasis deals quarter damage.
MEDIUM (humanoid) - Max HP: 100, AC: 18. When medium, the Krasis deals half damage.
GARGANTUAN (base size) - Max HP: 300, AC: 16
Regenerative. At the start of each of its turns, the Krasis regains 10% of the max HP of its current amorphic form. Additionally, once a Krasis has been reduced to 0 HP, if any body parts are left intact the Krasis can regenerate fully from the body part over 24 hours.
Siege Monster. The Krasis deals triple damage to constructs.
Multiattack. The Krasis attacks 6 times on each of its turns with its tentacles.
Tentacles. Melee Weapon Attack: +12 to hit, reach 30 ft., 1 target. Hit: 33 (8d6 + 6) piercing damage. The creature hit must succeed a constitution saving throw (DC 17) or be poisoned and paralyzed for 1 minute. The creature can repeat this saving throw at the end of each of its turns, ending the effects on itself on a success.
Description
The Destructor Krasis is a hybrid frog-octopus, combining agility with dextrous limbs and a lethal venom. Originally developed as a swarm control siege engine designed for combat against entire armies, the destructor is perhaps the most lethal of all the Category 5 Krasis.
