Audited Wilderness red deadly spider spawns (Overgrown Village)
The wiki claims that there were 9 spawns here, OpenRSC has far more. There are reasons to believe the 9 number is realistic, it was added to the wiki by Rsc 2001, who has various RSC+ replays recorded in the area.
He spends some time killing the spiders, allowing us to make quite good guesses at the spawns by watching. One spider is guarding the gold ore spawn, while several are guarding the steel plate mail legs. Other spawns are distributed around the eastern side of the village - that's why they don't escape through the hole in the west very often.
Additionally, we know from config46.jag that deadly red spiders have a wander radius of 10 tiles.
This is in a separate MR since it does not use the same maps27.jag data source.
