Chromaforge is a modpack intended to go into blind, the following is spoilers for what this mod adds:
Custom enemies: Rat, Silverian Abomination, Armed Worm, Long Spider
A full OST included in this mod. Music is dependant on biome for the most part, with exceptions in the music for mapstones, transit, and 2 cutscenes at the beginning and end of the game
Custom system for mocap NPC's to have dailog when interacting, as well as Crafter NPC's which are found in Sidequestia
Summonable mountable horses which can be found in the wild
Benches from handcrafted will reset enemies, heal, and set spawn
Colored skills for each enemy color type than will level up when the player kills an enemy of the same color
Integration with MTR mod: When the player rides an MTR train, the map opens (because the train can move so fast it can be disorienting). PIDS and trains also display the line name instead of the terminating station for world cohesion. Getting on a train also reduces render distance and holds some Luxium rendering to improve reliability
This mod is also what controls the intro and outro cutscene sequences the player experiences
The keybinds screen has been replaced with a much simpler binds due to, yaknow, modpack shinanigans. Of course on this screen there is still a "view all keybinds" button, as well as a second tab for controllers.
Integration into Sodium such that the player can choose a graphical preset that goes through the most intense mod's settings since they're all in different overwhelming configs.
Various other compatability fixes for Epic Fight, Parcool, Distant Horizons, Luxium, MTR and others.
