Looking back on this now, I feel like Necrocyst should be found in Mortis from Last Judgement since Blastocyst appears as a degraded boss in Mortis (just recolor him to fit Mortis better, maybe edit his attacks, and you're good to go)

Nevermind, maybe it was reworked foes, according to the console

When both this and stageapi are on, I get a weird visual bug when I start my run and it is Burning Basement on Greedier!

fwiw I think rotgut is easier than this one so I really like this idea and the fight seems really cool

Dope asf boss with a cool design idea
But it's way to easy for a corpse boss
I could see this dude appearing on depths but corpse?
I dunno about that one chief it's too late in the game at that point for him to put up much of a fight.

A for effort tho.
Wonderful design.

I don't know why recently some of new entities are randomly crashing the game and the log doesn't even show why it's happening, and this bug is recent, so It was probably created with the recent updates, I don't have much to do about it since the log doesn't even tell what's wrong

cool boss but shit crashed my game a few days ago

What? A binding of isaac mod boss that's actually fair and well telegraphed? That's unheard of! How outrageous! Death sentence!

yuqingzhitian hi, I don't want to be harsh not responding to your request, so I will be honest, I'm currently tired of updating my other mods with the exception of the repentance eternal edition mod, I just got tired of updating mods and I occasionally update the repentance eternal edition sometimes because it's the mod that I most like

Custom Stage API now supports the item Vanishing Twin, so hope you could update your bosses to supports it too.

Game crashes when issac get stumped by first split.
You know, the moment when 2 spawn, merges into 1, dies and split again.

I think the first phase could use more hp and the second phase attack where it jumps around the outside could use a few more bullets but other than that very cool!

always good to see the corpse floor getting some love

nice

Blastocyst but
But bitch

WOW

really cool stuff !

love it, glad to see a new corpse boss

that swap place attack is sick

oh okay

RedStinger665 it's crashing? strange, try to fight the boss again, and when it crashes go to:

C:\Users\Your PC User name)\Documents\My Games\Binding of Isaac Repentance

and open the file called 'log.txt', in the last lines will appear the reason of that crash, then post here the reason of the crashes

@JudeInutil Custom Stage API (for many, including myself) is known to crash a lot for unknown reasons. It sometimes crashes for me when starting a run on the first frame.

@Brishen The game itself doesn't support custom boss rooms and as such, Custom Stage API is the only way that you can add custom bosses to the game (which in my opinion is definitely something that should be added to the base game).

I really like this, a corpse alternative to blastocyst is fitting, and the fight is unique! Keep it up!

For some reason it crashes on me when it does the jumping around the room attack

Really cool boss! Fits the game well

Thank you for making more bosses and adding variety to the game. You're the reason why we have a few more hundred hours in this game.

Not lost friendly

That's a really nice mod, i love that he work together with his other part
The only thing i would do is to polish the sprites a little bit more and maybe change the name of it
otherwise great boss, keep up the good work !

un 'blastocyst" qui a l'air bien venere! j'adore .w .

Love seeing you making more bosses to this game. This one reminds me of sister vis with their conjunction attacks. Keep it up, your doing great!

@Раконорождённый other than continue run issues, I dont see anything wrong with StageAPI

@Brishen StageApi is bugged AF and it causes to crash a lot of time
But mod itself is cool

I really like how your bosses work. thanks for the cool bosses! also, I don't see the problem with needing Custom Stage API
