Hello, I am in the building with the yellow dotted wall border and every time I try to go past the yellow dotted wall border, a 280,000 HP enemy comes and kills me. I managed to not get killed only with a randomizer mod + fargo mod that somehow got me the Soul of Eternity by random.
I could not mine through the yellow dotted blocks so I used the right click on map feature provided by DragonLens mod. What boss I need to kill to access that normally and what pickaxe to break the yellow dotted blocks? Skeletron? WOF? Moon Lord? IIRC even when I have beaten ML I could not access the lower rooms without the 280,000 HP guardian appearing.
If this mod has a wiki, can you link it here?
