Clover (Young)

Legendary Resistance (3/Day). If Clover fails a saving throw, it can choose to succeed instead.

Magic Resistance. Clover has advantage on saving throws against spells and other magical effects.

Amphibious. Clover can breathe air and water.

Dense Carapace. Any time Clover is targeted by a spell that requires a ranged attack roll or a normal range attack, roll a d6. On a 2 to 4, Clover is unaffected. On a 1, Clover is unaffected, and the effect/attack is reflected back at the caster as though it originated from Clover, turning the caster into the target.

Siege Kaiju. Clover deals 3x damage to objects and structures.

Regeneration. Clover regains 4d8+18 Hit Points at the start of it's turn if it has at least 1 hit point. If Clover takes Radiant or Psychic damage, this trait doesn’t function at the start of his next turn.

Sunlight Sensitivity. While in direct sunlight, Clover can't see past 120ft, and it has disadvantage on ability checks and saving throws.

Multiattack. Clover can use its Frightful Presence. It then can make five attacks:  a bite, with its Arm,  with its Legs, and with its tail. 2 at most with each Body part and 1 bite.
It can use Swallow once a creature is grappled by Clover's Bite or Using a Legendary Action.

Bite. Melee Weapon Attack: +17 to hit, reach 10ft., one target. Hit: 34 (4d12 + 8) piercing damage. If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the Clover can't bite another target.

Leg claws. Melee Weapon Attack: +17 to hit, reach 20ft., one target. Hit: 26 (4d8 + 8) Piercing damage.

Monstrous Arm. Melee Weapon Attack: +17 to hit, reach 10ft., one target. Hit: 30 (4d10 + 8) Slashing damage.

Tail. Melee Weapon Attack: +19 to hit, reach 20ft., one target. Hit: 22 (4d6 + 8) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.

Frightful Presence. Each creature of Clover's choice within 150 feet of it and aware of it must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if Clover is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to Clover's Frightful Presence for the next 24 hours.

Swallow. Clover makes one bite attack against a Huge or smaller creature it is grappling. If the attack hits, the target takes the bite's damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside Clover, and it takes 36 (8d8) acid damage at the start of each of the Clover's turns.

If Clover takes 45 damage or more from creatures inside it or 135 from outside damage, on a single turn.
Clover must succeed on a DC 24 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the Clover. If Clover dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 30 feet of movement, exiting prone.

The Clover can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Clover regains spent legendary actions at the start of its turn.

Detect. Clover makes a Perception check with +8.

Attack. Clover makes one Leg claw attack or tail attack.

Move.  Clover moves up to half its speed.

Chomp (Costs 2 Actions). Clover makes one bite attack.

Eat. After a Chomp, Bite, or Monstrous Arm attack (<-Cost 2), Clover may attempt to Swallow.
