[Louro]

The mutant master is boring. And dangerous too, but mostly boring.

Ranged poisoning attacks, with AC 19 and resistance to everything. It would take forever to bring it down, assuming the lv9 party can, which I doubt.

[OrangeK]

Suggestions? My first time making something new
The Mutant Master is a modified Cambion, the only resistance i changed was FIRE to ACID.

Im shooting for a CR 9.

[OrangeK]

Also, i plan on using this monster with a Part of 5 @ Level 5.

I appreciate the feedback.
How do you feel its boring?
How would you spice it up?

Basically the lore behind this guy is that it was a Wizard who was desperately seeking extensions of his power (to save his sick and comatose daughter)
and ended up contacting an entity from another plane, who granted him with "power", but at the cost of his sanity, enthrallment to the entity and an insatiable hunger for power.

The Mutant Master will be the boss in a dungeon where he has townsfolk captive, getting transformed into Lesser Mutogorgons (i dont like the name, but was in a bit of a rush to make these guys)

for visual Inspiration i was looking at the art for "Simic Manipulator" from MTG - Gatecrash.

My thoughts:

Mutant Master
STR DEX CON INT WIS CHA
18 (+4) 18 (+4) 16 (+3) 12 (+) 12 (+1) 10 (+0)
Proficiency bonus seems to be +3, so INT saving throw should only be +4


2x Daily Reaction – Biotic Armor. The AC of the Mutant Master includes its Constitution bonus.
No duration listed. Is to only to the triggering attack?...until the end of the current turn?...until the start of the Mutant's next turn?


Acidic Blood – Whenever Mutant Master is hit with Bludgeoning or Slashing Damage, all creatures within 5ft must make a DC 12 Dex. Save. 10 (2d4+2)
Acid Damage on a Failed Save, Half as much on a successful Save
Seems more appropriate for that to trigger when hit by Piercing or Slashing, not Bludgeoning.

Made those changes, thank you!!!

I also trimmed the Resistances down to just Acid Lightning and Poison.

Actions

Acid Ray. Ranged Spell Attack: +7 to hit, range 120 ft., one target. Hit: 16 (3d8+3) Acid damage. If the target is a creature, it must succeed on a DC 15 Constitution saving throw against disease or become poisoned until the disease is cured. Every hour that elapses, the target must repeat the saving throw, (1d10) Poison Damage on a failure. The disease is cured on a success. The target dies if the disease reduces its hit point maximum to 0.
Why is it a saving throw against Disease for a Poisoned effect? Some things are immune/resistant to disease, others to poison. Pick one or the other for consistency.

Mutant Domination. One humanoid the Mutant Master can see within 30 ft. of it must succeed on a DC 14 Intelligence saving throw or be magically charmed for 1 day. The charmed target obeys the Mutant Master spoken commands. If the target suffers any harm from the Mutant Master or another creature or receives a suicidal command from the Mutant Master, the target can repeat the saving throw, ending the effect on itself on a success. If a target’s saving throw is successful, or if the effect ends for it, the creature is immune to the Mutant Master’s Mutant Domination for the next 24 hours.
This seems too powerful. Fail two saves and you can be forced to kill yourself.


Experimental Regeneration – Recharge 5/6 – The Mutant Master uses its Mutant Physique to rapidly regenerate any lost limbs and regain 2d6+6 HP
As a full action, this seems week.


Mutogorgon
Acidic Blood – Whenever Mutogorgon is hit with Bludgeoning or Slashing Damage, all creatures within 5ft must make a DC 12 Dex. Save. 10 (2d4+2) Acid Damage on a Failed Save, Half as much on a successful Save
See above.


Multiattack. The Mutogorgon makes Two attacks its tentacles, Or it uses Acid Throw or Experimental Regeneration
This is unclear. It that two Acid Throws? If not, why is it listed as part of Multi-attack. Same with Experimental Regeneration.


Greater Acid Throw. Same as above with Poison/Disease.

Ooops, missed this,. Good Point. Thanks.

This is as it was written for the Cambion, the only thing i changed was from CHA save to INT save.
Ill tweek this.




As a full action, this seems week.
Make a Bonus Action, or up the Healing Die??



See above.
Already Fixed



This is unclear. It that two Acid Throws? If not, why is it listed as part of Multi-attack. Same with Experimental Regeneration.
