Need help with monsters.

[Peanut]

I need help. (if you didnt already geuss)

I am making a wad, a wad file for heretic.
I put in a maulotar and every time i kill it, all the monsters die in the level.

What do i do?

I want the maulotar in the level but i need to find out how to make it were when the maulotar dies, the rest of the monsters will not die.

Please help. thank you.

p.s i am making the wad to replace the e5m8 map. would that posibly be the cause?

Due to the fact that the boss is a level ending boss, such as Icon of sin, when the monster is killed the level should end. This however, in Heretic that is, when the bos is placed on a map designated as an em8, the episodes ending level. If you want to fix this make the level something other then a map 8 level and there shouldnt be any problems.
p.s refer to e3m7 in which there is a maulatour that during the middle of the level, and killing it doesnt end the level or kill all of the rest of the monsters.

Put it in E3M8, same sky texture, and killing a Minotaur should not kill the other monsters. The only problem is that the victory message tells you that you have killed D'Sparil. Or you could create a new actor with decorate that behave exactly as the Minotaur (I think it's just a few lines of code, I don't know how to do that, but most people here seem to be very skilled with that).
