CHANGES

EVOLVED BIOME MOBS

  • Emperor: When in its first phase, now shoots projectiles slower, but with higher damage output (This change is from V1.2 but I forgot to mention it).

STRUCTURES

  • Node: The Speed Node now increases Crimon Invaders' Speed by 35% instead of 25%.

CREATIVE MODE

  • /function cc_loot:crimson_survival_guide & /function cc_loot:everything: now give the Crimson Survival Guide instead of a chest containing the book.

TECHNICAL:

  • Movement Animations: Raptors, Harbingers, and Manglers now use a predicate to detect movement instead of using a marker entity. This change heavily reduces lag caused by these mobs, and now they will be able to exist in similar numbers to all other mobs before causing any major lag (for reference, my computer could handle about 100 of these mobs before lagging, and now can handle closer to 300, which is about the same for all other Crimson Invaders). If there were a lot of these mobs in your world, run this command after downloading this version: /kill @e[type=marker]

BUG FIXES

SYSTEMS

If the Max Infection Radius config option is enabled, when a Raid that spawned outside of the Radius is successful, another infection event will now trigger.

MOBS (GENERAL)

  • Custom Mob Sounds: Any mob with custom sounds will now make a hurt noise when damaged by an Immunity-Frame-ignoring attack (This change is from V1.2 but I forgot to mention it).

CRIMSONIFIED & DECAYED MOBS:

Fixed an issue introduced in V1.2 for 1.21.5 caused by the Phase progression nerf that caused Decayed Mobs to spawn in phases that they were not supposed to.

INFECTING MOBS

  • Bloodlink: When a Bloodlink Spawns in, it will no longer force-replace the block beneath it with Basalt, and will now only do so to the same list of blocks that Titan Drills can break.

PRIMAL BIOME MOBS

  • Sky Bomber: Now gives 0-3 items upon death instead of 0-5, to match the drops of all other Primal Biome Mobs.

CRAFTABLE ITEMS

  • Crimson Survival Guide: Beacon Purifier's Crafting Recipe is now fixed to say Diamonds instead of Diamond Blocks. Thank you to melivo on Discord for finding this issue.

  • Dried Pummeler Tendril: Its 1.21.1 Potion effects now match the 1.21.5 varient.

  • Crimson Repeller: Its particles when active are no longer 1 block higher than they were supposed to be (1.21.5 issue

  • Purified Axe: In 1.21.5, will now will destroy some 0-hardness blocks just like it does in 1.21.1.

CONFIGURATION OPTIONS

Fixed a few minor typos where "cappped" was written instead of "capped"

TECHNICAL:

Fixed some 1.21.1 issues with the #crimson_curse:non_living entity tag.
