Hello. On start I will say that visually and overall nice idea for monster.
He fits with theme and graphics.
Congratz on this one and other mods you did. Mimic monster is one of my favourite one.

Monster in my Opinion for people who add really distrubing monster and are really to lose companions or adding other modded strong classes.


SPOILERS

but now about cons and other balanced stuff :
Moves" - i meet him at dungeon level 1-3.
Have 2 moves per round
-he's marking 1 or 2 targets.
- and massive damage from move (Finish them)
- meat shield - forces to be defended by other monster
-and always on end of turn using 'Collect prey'

For first few turns he was only marking and finishing with last move - Collect prey' - what btw dont take his action, its really unintuitive to get when you meet him.
But on round 6 he marks one of my 4rd position Jester, as second action using finish him - out of no where btw, he didnt used it once in 5 rounds - what did massive damagea already and then 3rd time hit him with move 'Collect prey'. And kills him.
Sad story for me, first death on my deathless till then run.

Conclusion:
-First of all monster like shouldnt come with 2 other Swines to help him. At least not for apprentice level dungeon. If he show up 2 strong swines - its gg for group without strong healer or some guard. Even then casualties will appear.
-If he appear with lets say butcher swine. Then we can came to situation where Boss- triple atack one target (like in my situation) - Marks - use Finish him also on same and other row - and Collect prey. Adding action of other swine's with him comes to situation where 1 target can be hit 5 or 6 times if also gets bleeding/blight. And fact the finishing move comes always as LAST action in fight is not helping.
I know its its unlikely to happen that often but happens.
-quite high prot and stun immunity - to high in my opinion for aperrentice level - not letting you to distrupt his combo.
-and payout for killing him is too low compare to danger - onestly i had much smaller problems with Swine Prince or other those type of bosses with weaker team than with him.
I know payout is in trinket what give gold - due to not wanting issue with other trinkets/mods but in my opinion payout should be higher not 3,5k, maybe even double.
-maybe should appear only dungeon level 3 and higher due his kit
-He cant be suprised and our party is always suprised even due having high supprise party % ?
