CoFH Core adds several tweaks to the game. Most of these are optional and can be disabled.
Bows enchanted with Infinity work even if there are no arrows in the user’s inventory.
When a mob with a custom name dies, a death message is shown in the chat as if it were a player. This is enabled by default.
If color blind textures are enabled, features that rely on color use different textures for people with color blindness.
A configuration option is provided to completely disable all particles, even those that still appear when the ‘Particles’ setting is set to ‘Minimal’. This option is provided to increase performance on starch-based platforms.
