Jagras, Shamos, and Girros from Monster Hunter!

[Psyche]

So I saw some monster hunter fans on this forum recently, so I decided to make some humanoid Girros, Jagras, and Shamos as the leaders of a cities defences (they are the greats though great shamos and jagras look like normal. They have minions like the greats do as well.)
These are individual characters, I will be making races and Stat Blocks for the standard Jagras, shamos, and Girros as well as the races
For the moment all I have is The great girros, so bear with me over the next few days as I make more.

Terran(the great girros): Terran is brutal, powerful, and stands for no insurgence within his part of the city. He runs the Effluvian defence force, making sure that the city runs in perfect order without any outside force wrecking what he considers a utopia. However, while off duty, his demeanor changes to that of a gentle giant. No matter on duty or off, he hates young people (people in between 18 and thirty)

Response to the crunch:

I'm getting a defensive CR of 18 and an offensive CR of 24, which averages out at a total CR of 21. The offensive CR is higher if we calculating him biting a target, that target failing their save, and then him wailing on it for the rest of the round. Since they're paralyzed, he can guarantee they start their turn within 10 feet, and wail on a paralyzed PC again on their turn.

Mechanically, this sounds like Terran is a terror at close range and a joke as long as you can stay away from him. If the goal at the table is the PCs try to sneak around him and you want a hypothetical chance to escape at being caught this could work pretty well.

Response to the fluff:

A grim guard is kind of cool, but I'd focus either on making him more able to do the job.

For ideas for things Terran can do beside damage, some kind of buff for your regular Girros as an action or bonus action might fit well. Maybe some damaging miasma that follows him around (based on the one Vaal Hazak has) as a mark of him being an authority figure in the city?

At an absolute minimum (given he's a humanoid girros) I'd give him some paralysis javelins for a bit of range. That makes him a bit more fearsome at range, as he can trap a PC beside himself without needing to get within 5 feet in the first place.

That is a lot of stuff for a early game mob, holy heck. That’s something like CR 20 something eyeballing it. I can’t picture anything related to those as much higher than CR 5-7 personally

I'm not in a mood to do the math again right now, so I'll just leave some qualitative suggestions.

Venom spit(Recharge 5-6) He chooses a point within 120ft of him, each creature within 10 ft of that point must succeed on a DC 23 Con save or be paralyzed until the beginning of their next turn.
Astounding Leap(Reharge 6) : He moves 90ft, any creature within his space must succeed on DC 22 Dex save, taking 4d8 bludgeoning damage on a failed save, or half as much damage on a successful save. Either way, the creature is pushed out of terran's space.
Reactions: When girros hits a creature with an opportunity attack, its speed becomes zero and girros regains his reaction for this round.

These seem like an improvement design-wise. Although I would steal the language used for the Gelatinous Cube's Engulf for Astounding Leap. Something like the following:

Terran moves up to 90 feet in a straight line. While doing so, he can enter Medium or smaller creatures' spaces. Whenever Terran enters a creature's space, the creature must make a DC 22 Dexterity saving throw.

On a successful save, the creature can choose to be pushed 5 feet back or to the side of Terran. A creature that chooses not to be pushed suffers the consequences of a failed saving throw.

On a failed save, Terran enters the creature's space, and the creature takes 18 (4d8) bludgeoning damage and is knocked prone. Terran cannot end his turn in another creature's space.

Multiattack: This creature makes 2 javelin, 1 bite and 2 claw, or 2 glaive and 1 flip attacks
Javelin: +8 to hit reach 5ft or range 20/60ft 1d6+5 Hit: The hit creature must succeed on a DC 11 Con saving throw or be paralyzed until the end of it's next turn.
Claw: +8 to hit; Reach 5ft; 1d6+5
Glaive: +8 to hit; Reach 5ft; 1d10+5
Flip: +8 to hit; Reach 5ft; 1d4+5
Bite: +8 to hit; Reach 5ft; 1d8+5; Hit: The hit creature must succeed on a DC 14 Con saving throw or be paralyzed until the start of it's next turn.

The Claw and Flip attacks feel superfluous. The attacks all have +8 to hit and very slight changes in damage, so you really don't need five separate ones. In Monster Hunter the different attacks have different ranges and wind-ups, but you just don't get the same effect in D&D.

Reactions:
Polearm Master: Girros makes an opportunity attack against a creature within his reach.

Was this meant to be bonus action? If not, it should have a trigger telling the DM the conditions under which the Girros can take this reaction.
