maybe it's just me but my world is pretty thoroughly explored by the time I get to hardmodemy gameplay directly following WoF generally consists of going back through old caves with spelunker potions, slowly progressing up to the tier 3 hardmode metal
or get lightningspark boots, kill like 10 crimson mimics, get the dart pistol, make 4000 ichor darts, demolish everything in hardmode including bosses
I dont have the crimson in my world though
tough luck
how can you explore the majority of your world in pre-hardmode, we must play the game entirely different because i try to rush to beat the wof (by normally skipping the jungle, queen bee, and hellstone armor) and then buying a shotgun,and going from there
me and my friend normally don't rush anythingwe just take our jolly good time exploring and adventuring, killing things along the way
wof is really the only thing i try to rush, because pre-hardmode is boring imo
more interesting than chlorophyte grinding
loving medusa keeps stoning my ass, half the time she won't even be in her marble biome or I won't even see her at all and then bam stoned.
