A single video, have not attempted to recreate this.
Weekly event that spawns two weaker enemies, Hunger in the Dark, ringing the bell to spawn the troll.
Only… The troll spawned somewhere else entirely and I was also able to escape without needing to kill it?
Killing the troll was never necessarily. If the whole team crossed the bridge while the troll is on the bell side, the bridge will explode and leave the bot back.
If you do that with bots they will even teleport to you even when they are too at the bell. Using this and Handmaiden Invisible dash is the easiest way to get the 15 seconds kill challenge. The changed troll spawn shouldnt happen though unless Fatshark added some variation for the final.
