Thank you for the answer. Now that I paid attention, it even shows that on the map when you test the level (4 creatures merging into one). As I'm not yet familiar enough with entitesAt function, I spawn the creatures instead as that works as well in my case.

..but now I've encountered a different problem concerning patrols. I try to change the AI state of one of the skeleton patrols, but it apparently changes the ID of those things O.o I've used this script succesfully with other non-patrol/swarm creatures, but with these swarm creatures it gives me an ...

Yes, that's it! I made my patrols consist of special skeletons and searched for them. Now everything works as they should. Thanks for an advice.

Ok, the swarms/patrols are still bugged somehow. I tried the script and was dumbfounded when it acted the same way again, it just kept spawning patrol after patrol. I double checked the script. I changed my custom patrol to vanilla patrol with same results. I changed the patrol to skeleton warrior. ...

Ok, now that the spawner bug was corrected I could continue modding the place I wanted to be under constant patrol. But lo, the script keeps spawning patrol_1, whenever I step on the pressure plate, even when it finds the monster on the area. And now I'm lost again, what is wrong in my logic? I test...

I'm here again with my nooby question. Sorry. Is it possible to remove a block with a hidden pressure plate? I've set a block in a passageway, but only want it to be temporary, so I've inserted an invisible/silent pressure plate, activated by party only, the next step after the block. That's to giv...

I think, but I'm not sure, that LoG handles warriors and patrols as different monsters altogether. As LoG's skeletons don't merge into patrols as for example in Dungeon Master, warriors never come into same square with each other (except if you spawn them into one apparently :D ). Same goes for othe...

I'll post my findings also here. It seems that monster patrols/swarms can't be spawned. At first I thought this was some kind of scripting error on my part, but then I tested it on a new clean dungeon with just a pressure plate activating a spawner and it doesn't work either. So is this a bug or a f...

Ok, it seems there's something preventing the spawning of skeleton patrol. I tested it with crab and it does work fine, but when I change it to skeleton_patrol it doesn't work anymore.. edit: further testing proves the same thing for skeleton_archer_patrol. edit2: I tested it without any script in t...

Thank you! Good to know it's not the script then at least. But yes, that was part of the original question, is there something preventing the spawning of custom monsters? When I place the custom monster on the map, it behaves normally as it should. I just can't spawn it. It doesn't even try to give ...
