LF Quests/items/objects/event scripts that spawn mobs

[dognip40]

As the title says, I am looking for items, game objects, quests or quest scripts that start an event that will spawn hostile npcs. Particularly stuff that would've been.available in patch 1.12.1. I've went through numerous databases and wikis and found quite a bit of what I was looking for but it's hard to search something so specific as "does using this or that item or object spawn a mob/does this quest start an event which spawns mobs". The reason I'm looking for such imfornation is to find potential quests or objects that can be exploited to spawn or summon more mobs than are intended .

Thanks for reading
