The Meowsma has an 80 foot climbing speed and a 40 foot walking speed.

[Dude this thing is absolutely terrifying, Idk if VitusW still looks at this thread but it’ll definitely be later than Eungeon 51 if it appears in my campaign, or at all lmao. I think CR 15 is kinda low considering some of it’s powers, but it’s more of a tool to calculate stuff for official, balanced monster used by DMs worldwide, rather then a mishmash monster that’ll probably only get ran by me (it’d be cool if you guys ran it tho if you want!), so I’m really not too bothered about CR at all since it doesn’t mean anything.]

 (I'm just surprised it still kept to a somewhat similar vibe of the actual Meowsma I have made. XD)

Multiattack: The meowsama can make two arm attacks. Each attack must be made with a different arm 

Upon being hit by an attack with the Firbolg arm, the target must make a DC 15 STR save or suffer the effects of the Earthbind spell.

*note: The Meowsma doesnt choose what arm, it's random like beholder eye rays. I'm fine with changing that, but if so the human arm has to be given a use by someone instead of no effects.*

The bugbear arm has a range of 10 feet, being able to stretch and extend to a bugbear's true arm length. Additionally, being hit by it disorientates the victim. The target must make a Wisdom save or the Meowsma is invisible to the target until the end of its next turn.

The human arm carries a magical longsword, specifically a Longsword of Wounding.

(And yeah, having which arms used randomized actually seems better than it getting to choose.)

An ooze made with poo.... which spreads poo when walks.... and attacks like a Volcano.... spitting poo from the top of its body ( I still dunno if Ooze are either gendered or truly neutral gender ).

Magic-casters who seeks more bat guano would be interested in such ooze poo... hahahahahaha..

Sounds chaotical and weird, huh ????

 *If we randomize it, I'd prefer if the human arm is just the basic attack. Kinda as a punishment for rolling a Nat 1.*

 We're already fleshing out a different monster. Look in the rules.

 Ah, OK. That's fine.

It has proficiency in Wisdom saving throws

The Meowsma has a Wisdom score of 15.

The Meowsma: Huge Abberation 

Description: The Meowsma has eight arms from assorted races: one human arm, one dwarf arm, one elf arm, one orc arm, one firbolg arm, one tiefling arm, one bugbear arm, and one goblin arm. It has the nature of an Eldritch Horror, though it natural sounds like a distorted and otherworldly cat that matches it’s head, which is one of a mangy cat that looks like it’s been on the street for years, and the rest of its feline body follows suit, as it is equally emaciated, long and spindly from what looks like malnourishment. The Meowsma is a formidable foe, using it’s ability to phase in and out of existence to sneak up on prey, or lure them in with the cries of previously devoured adventurers using its Mimicry trait. Once within combat range, it uses it’s highly effective miasma to either immobilise foes, or wreak mental havoc on them with illusory threats.

Stats

STR: 24  DEX: 15  CON: — WIS: 15 INT: 25  CHA: —
Saving Throw Proficiencies: WIS

AC: 18   CR: 15   PB: --

40ft. Walking Speed, 80ft. Climbing Speed

Traits

Mimicry: The Meowsma can mimic any sounds it has heard, including voices. A creature that hears the sounds can tell the are imitations with a successful DC 14 Wisdom (Insight) check.

Spider Climb. The Meowsma can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Special Equipment. The Meowsma carries a Longsword Of Wounding in its human hand.

Corruption. Once the Meowsma has taken (undecided) points of damage, it begins to leak corruption. Any creature that starts their within 10 feet of the Meowsma must make a DC (undecided) saving throw or gain one level of Exhaustion. If a creature dies whilst it has any levels of this exhaustion, it is resurrected as a Shadow on the Meowsma’s turn.

Actions
Multiattack. The Meowsma makes two random attacks with two of its eight arms. Roll 2d8, and reroll 1d8 if the numbers match, to determine which arms the Meowsma attacks with. The arms correlate in order of how they are presented below with the numbers on the d8.

Human Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: 1d8 + 7 slashing damage. At the start of each of the wounded creature's turns, it takes 1d4 necrotic damage for each time you've wounded it, and it can then make a DC 15 Constitution saving throw, ending the effect of all such wounds on itself on a success. (See Longsword of Wounding for full details)

Orc Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage, and any creature hit that is Large or smaller has to succeed on a DC (undecided) Strength Saving throw or be pushed back 10 feet and fall prone.

Tiefling Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage, and the creature must succeed on a DC (undecided) Constitution Saving throw, or take (undecided) fire damage at the start of each of the Meowsma’s turns. At the start of the creatures turn, they can repeat this saving throw. On a success, the effect ends. 

Goblin Arm.  Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage, and the Meowsma steals one item off of the creature. This can be armour, weapons, objects or gold. The player must succeed on a Wisdom (Perception) check contested by the Meowsma’s Dexterity (Sleight Of Hand) check. On a success, the Meowsma does not succeed in stealing the item, and on a failure, the item is stolen without the creature realising.

Firbolg Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage, and the creature must succeed on a DC 15 Strength saving throw or suffer the effects of the Earthbind spell. 

Bugbear Arm. Melee Weapon Attack: +(undecided) to hit, reach 10 ft., one creature. Hit: (undecided) damage, and the creature must succeed on a DC (undecided) Wisdom Saving throw, or the Meowsma is invisible to the creature until the start of it's next turn.

Elf Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage

Dwarf Arm. Melee Weapon Attack: +(undecided) to hit, reach 5 ft., one creature. Hit: (undecided) damage

Miasma (Recharge 5-6). The Meowsma exhales a miasma of red smoke in a 30-foot cone. Roll a D4. On an odd number, each creature in that area must succeed on a DC 13 Constitution saving throw. On a successful save, the target is paralysed until the end of it’s next turn. On a failed save, a target begins to turn to stone and is paralysed, and must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is petrified until freed by the Greater Restoration spell or other magic, however they are still conscious and aware of their surroundings and therefore can feel pain, though they still do not take damage like regular Petrification. 

On an even number, each creature in that area takes (undecided) psychic damage and is frightened of the Meowsma for a minute, as they suffer horrifying hallucinations.

Bonus Actions 

Ethereal Jaunt. The Meowsma shifts from the Material Plane to the Ethereal Plane, or visa versa. 

Legendary Actions

The Meowsma has a +10 to hit on all of its melee attacks.

So a +3 proficiency bonus, as it has a +7 in strength.

I feel like it would be higher with its current strength and CR.

The dwarf arm makes the target become 1 size smaller, as well as reducing its speed by 10 feet, both until the start of the Meowsma's next turn (with a minimum of tiny size and 0 feet speed).

*Ngl I didn't really have much ideas for dwarf. I got none for elf.*

Reaction to bleed and corrupt chars when it takes enough damage
