For me it's crimson spreading and giant tortoises

Crimson in the underworld, it f*ckin sucks

yeah, i agree. crimson is nice, but corruption has better music. its a hard choice.

Waiting for your mods to load. (im a player who plays modded terraria more)

4 hours later and calamity's still loading the first boss frfr

i don't hate the evil biomes themselves, but trying to find that one tiny bit of it left when you're trying to use the clentaminator/terraformer is painful
but i agree, giant tortoises are annoying, especially when they quickscope you from go***mn low earth orbit

When you first start Hardmode and damned Moss Hornets start swarming you

WHEN THE EYE OF CTHULHU WAS AT 32 FREAKING HEALTH AND I DIED

Rod of discord grinding

Dying to green slime

Twins randomly spawning right after wall of flesh

The fact that NOT ONCE, IN A SINGLE CANON PLAYTHROUGH, have I got the Rod of Discord.
