D&D 5E Created Ooze boss would like some feed back on it thoughts critiscims welcomed

[Nightbeat84]

Little backstory on why i created this boss monster i am currently running Out of the Abyss campaign and my party is now facing the Ooze onslaught about occur in Blingdenstone. The big bad is the pudding king and i found hes stat block underwhelming and anti climatic. There is a big build up to reach this point so i wanted a more memorable fight. There are no boss monster in the ooze category. Also he suppose to be like an emissary of the demon lord Juiblex. So i created this guy my party is currently lv 8.
Edit. So here is version 2.0 of Garos. Also this model was created by the very talented CometLord i got it as a patreon reward and he also has a store online to purchase the files so shout out to him. Comet Lord Miniatures

Garos is immune to Slashing but does not split. I would caution against making a major enemy immune to such a staple damage type.

312 is a lot of HP. And then there is the Regeneration. This fight is going to be a slog.

Magic Resistance plus at will Blur (and able to cast a spell along with 2 attacks) makes him hard to hurt.

Garos has up to 5 attacks/round which deal 36 damage each plus a spell plus summoning.

How are you arriving at CR 12? This looks to be much higher than that.

Looking at pg 274 of the DMG:

Garos has a Defensive CR rating of about 22.
Garos has an Offensive CR of about 24.

So that puts Garos at about CR 23.

(Which I think is a bit on the conservative side given not all abilities were accounted for in that calculation)

Very nice.

Its CR is a bit low though, although you first think it be a bit squishy bec. of AC14, the whole list of immunities and resistances plus its dissolving attacks make it highly dangerous. I suggest CR15-16 for it.

You can use this one as a solo mob.
I suggest that magic weapons and armor are not afflicted by its destructive attacks.

You should do the following also: Lower its AC to 10 but up its HP to 800-1000 or so.
Make the party hit with every melee or ranged weapon attack and watch their horror as the thing still does not get down .

Also alter darkvision to tremorsense, it has no vision in a common way. That would also make it quite immune to sneak attacks.

Also give it a weakness, I suggest cold.

Edit: also leave out the psionic/spell attacks, give it the possibility to communicate psionically if you want RP around it. A thing like this does not need magic to enhance its attack capabilities.

I should have mention the web based program that I use when you put he CR up higher hes profiancy goes up which I dint want. So you are correct he is definitely not a cr 12 monster also the minions will only have 1 hp i pilfer the minion rule from 4th edition. They will have all there stats but only require 1 hit to kill them. Nust for action economy reason and to be annoying to spell casters in the back row

Are magic items immune to the dissolving effect? Because there's otherwise nearly no way for anyone to melee this guy down, and he's immune to most forms of spell damage.

Unless there was something to defend, I would argue at the table for hitting him with Slow then simply running away.

Does it speak? Interact with the party? Or is it just a big numbers-slog of HP to work through with no personality or character? What's going to make this fight interesting or memorable besides "Ugh, it was an ooze+rust monster with a ton of HP and we lost all our stuff."?

Hmm ya I dint understand the slashing immunity thing in the ooze stat block like black pudding until now so I shall remove it. Thank you for that. The acid damage is 1 damage dice h

I did not understand about why other oozes had immunity to slashing until now thank you lol. You turn a light on my head I will definitely remove that immunity. Also I did some calculations my players on average can do 133 damage a round and I wanted him to last longer then 3 rounds of combat so that's what the regeneration and higher health is for. I am aware that a couple of bad rolls can definitely affect the damage output and what not so as any DM you can use monsters health as a gauge by raising or lowering if things are going terrible for your players. The blur spell was an after though which I think I will remove and put in more Illusion magic maybe or remove magic all together. The acid damage is 1 damage die higher then a black pudding but maybe I should lower it back to 4d8 maybe?

Seems well written, but I'm concerned that the enemy is just a pile of HP. Nothing really tricksy or interesting except 3 Compulsions and a Project Image. I would like to see something like...

Gush: Garos expels a sickening green fluid in a 20 foot radius. Anyone that attempts to move across the fluid must make a DC14 Acrobatics check or slide along the fluid to the opposite end. Recharge 5-6.

Ya I plan on RP'ing with him. The party did complete a quest that gained them some oil to coat there arms and armor to resist the corrosive nature of oozes and I ruled that magic items would be affected by it. I have had them fight oozes that did affect there stuff as a method of communicating that they should find a way to protect themselves. I'm strong believer that with some strong foreshowing that the party should prepare to counter powerful effects but if they choose to ignore it and charge head long into danger there is repercussions to there actions and there is always the option to retreat in the face of a great danger that they where ill prepared to face. Is that to harsh? I don't think so. I set up encounters for the story not balanced that the party thinks that every fight they are going to win. that's my DM'ing style. I still consider myself noobish only been doing so for little over a 1 year now. I did give an item that can weaken the monster if they decided to use it as well I feel like I have given them options and information to prepare for the conflict ahead of time

I might lower he's regenerate but I did some math and my party can do 133 damage on average a round. I was concerned that he would die to quick wanted to him to last longer then 3 rounds . With any monster with HP pool if it seems its becoming a Slog I can lower he's HP mid fight. I might even lower he's AC as someone suggest earlier. I do like that ability you suggested. I figured some enchantment or illusion spells could make him interesting I did not want really any attacking spells. Was looking for more mind control stuff more then anything else but that could be devastating for the party to turn one of there own against them? I do have a mini for this encounter he has 2 large hands and 2 smaller ones I wanted to figure something the smaller ones could do instead of pure damage hence the magic casting I will post a picture of the mini
