My god, how long has it been?
Sorry for the update drought. University essentially stopped all work on this mod for an entire year, but now that I'm finished with it hopefully development will pick back up. Maybe.
I decided to include two reworks in this update, but chances are I go back to pushing one per update to release them more often.
This update mostly focuses on new reworks more than updating old ones. A smaller balance update may come some time later.

v0.6.0.0 published to Stable tML v2024.5.

Additions

• -Reworked movement code, there may be slight differences
  
• -Reworked phase 1
  
• --Biggest problem with designing early game bosses like EOC and KS are that you have to design the fights around extremely sluggish movement (no dash, weak vertical movement, slow acceleration). This is even harder if you try to compensate for melee's pitiful lack of range early on. It's why EOC has points where it doesn't attack.
  That being said, EOC is literally the first boss I've ever made/reworked, so I redone arguably its weakest part.
  
• -P1 Servants can no longer merge into one eye
  
• -Slightly reduced dmg of dashing servants
  
• -Dashes

• Skeletron
  
• -Reduced head contact dmg back to vanilla values (He was doing 150+ dmg in master my god)
  
• -Reduced hand base contact dmg from 30 to 22
  
• -Hands in master mode now "enrage" at 75% hp instead of 80% (similar to other bosses)
  
• -Other minor changes
  
• -Skull + Smash
  
• --Decreased base dmg of arena skulls from 28 to 24
  
• --Arena slightly bigger
  
• -Ring + Bone
  
• --Arena applies blackout & cursed again, cursed changes to withered weapon after Skeletron is beaten once
  
• ---This makes him more managable in swarms
  
• --Bouncing bones are now bigger but slightly slower
  
• --Bones when flung are now faster
  
• --Visual tweaks

• --Increased dmg of mega bolts in expert+ to be more inline with other projectiles
  
• WOF
  
• -Eye and mouth base dmg increased from 30 to 40
  
• -Hungry base dmg decreased from 40 to 35, initial launch speed is slower, tweaked reel back movement
  
• -Removed scaling laser dmg and made them do their max dmg from the get go

• --Might expands outwards even more
  
• Destroyer
  
• -Reduced dmg overall
  
• -Explosions produce less dust overall

Bugfixes

• EOC
  
• -EOC is now regular size, apparently EOC was 1.1x bigger than he normally was and I never noticed this.
  
• EOW
  
• -Explosive spit (NPC version) now has proper explosion sprite
  
• Skeletron
  
• -Fixed some hands being translucent when they shouldn't
  
• WOF
  
• -Cursed fire now properly starts invisible again
  
• Destroyer
  
• -Attempted to sync boss better in multiplayer

Also, for like the 5 people who's still around, I do read the comments (and thank you for the good feedback). I don't reply anymore since I don't check them all too often, so I end up seeing new comments some months later.
I tend to focus on the new rework first and only start tweaking older ones once its done.
