The 2.1.2 update made further refinements to the Brain of Cthulhu fight in Revengeance Mode, made several balance changes to items, and fixed a multitude of bugs.

Changes

Bosses

• Boss Rush now has a Tier 1 animation.

Brain of Cthulhu

• No longer deals contact damage while stunned, while transitioning to phase 2, during the downtime between charges, during the semi-circular ichor rain and blood shot attack, while spinning around the player during the Illusion Spin attack, or while invisible after fading out before the Illusion Trick attack.
• Decreased how fast Creepers spin around during the Creeper orbit attack in the second Creeper phase.
• Decreased how much ichor is released by the semi-circular ichor rain and blood shot attack. Attack now additionally fires blood bombs which can be hit with weapons at close-range to redirect them back at the Brain, dealing damage.
• Illusion Spin attack now waits longer before firing blood shots after illusions charge, fires the blood shots behind it instead of in front of it, and it now fires less blood shots in Revengeance Mode.
• Projectiles spawned from projectiles that ignore Illusion Brains will now also ignore Illusion Brains.
• Hitting an Illusion Brain now has an 8-frame delay before damaging and debuffing the player. Hitting the real Brain during this delay prevents this.

The Devourer of Gods

• No longer deals contact damage while flying away after laser walls in phase 2.
• Now disables the effects of Cinnamon Roll, and final phase portal charges now spawn laser walls in the For the worthy seed.
• Head and tail now take 2x damage from all sources in Get fixed boi instead of For the worthy.

  • Decreased phantasmal eye and phantasmal sphere attack frequency boost.
  • Decreased phantasmal deathray rotation speed boost.

The Old Duke

• No longer immediately spawns when the fishing bobber touches the water, and instead the bobber must be pulled to spawn him.

Polterghast

• Clone no longer deals contact damage while moving into its charge position.

Enemies

• Decreased Aquatic Urchin's spawn rate.
• Gnasher can now spawn out of water. Reverted AI changes made in 2.1.0.

Recipes

Resprites

• Resprited Terminus.

Reworks

• Reworked Nanoblack Reaper, it no longer rapidly throws homing nanoblack scythes that spawn nanoblades, and stealth strikes no longer make scythes spawn afterimage clones. It now throws a scythe which rapidly spawns hardlight tesselations which fire an instantaneous beam at nearby enemies; beams deal typeless damage and have an innate 150 armor penetration. Releasing left-click right as the scythe begins returning causes it to perform a light-speed carve through the closest enemy to the cursor. Light-speed carves have an innate 150 armor penetration, and if the release is timed within a 4-frame window, the carve gains +100% critical strike chance and can supercrit. The weapon does not have a traditional stealth strike; instead, right-clicking with enough stealth for a stealth strike will empower the next 30 throws of the weapon. While empowered, the weapon attacks 3x faster, and scythes rapidly spawn stacking slashes over an enemy but cannot perform light-speed carves. Buffed damage from 130 to 315, but nerfed use time from 6 to 19.
