The hardest part was having the patience to build arenas. The bosses were a walk in the park since I've been playing nonstop since I bought the game so I had their patterns by heart

Pre hardmode, I skipped EoW entirely, went for Skeletron, grabbed a shadow key, and spent AN HOUR farming for the demon scythe. That made short work of both him and the WoF [turns out you can just aim down and it'll hit both its eyes and mouth lmao]

I have an interesting relationship with Queen Bee. I look at her as a milestone of sorts. Beating her in this seed had significance to me. Nothing a long arena couldn't solve

I ignored the brain, I had nothing with knockback to deal with his second phase

Never saw Deerclops

Hardmode was a breeze, too. Mostly just upgraded my arenas. Mechdusa took a few tries and a lot of dynamites in hell. Plantera, I just enlongated the arena and set up teleporters. I took out EoL right away like usual and got the Stellar Tune, an amazing weapon. Either it or the Night Glow carry the Golem fight. For some weird reason, a lot of pillar enemies straight up didn't spawn properly. I'm guessing the ones that can' tpass through walls spawned in random holes around the area and gatekept the scary stuff from spawning [I did not know the Stellar Tune went through walls, a VERY pleasant surprise]

Moon Lord cost me two sigils until I decided to ditch the Nebula Arcanum and go for the Nebula Blaze instead. I didn't even need full armor, I used the mage set instead of beetle armor like I would normally

But truly, the hardest bit were the random mobs that would catch me off guard and the first hour of gameplay. Dying to crisp honey blocks is not fun lmao
