So, the past few days I've been trying to kill the WoF. Got myself a walkway built and everything, just couldn't keep the damage up. So, I spend yesterday and today collecting fallen stars for my star cannon and making meteor shot for my minishark and all that good stuff, reforged to get a modifier or two I want, that kind of thing. So, I go down and toss my guide into the lava so I can start fighting, and the goddamned thing is spawning behind me, going the opposite direction, and I'm instantly getting tongued. Am I doing something wrong? Because it's happened three times consecutively now, and I'm starting to get real pissed off.
This was happening to me when I tried to kill it last. Looked up on the wiki and it said the WoF comes from the closest edge of the world, and travels opposite the direction you're facing when you drop the doll.
So if you're on the far right side, wanting to run left, make sure you continue to face right until the WoF has spawned.
