Welcome to Foss! Foss is a world that is all about fighting custom and interesting boss battles, one after the other, to become stronger and stronger.

Details:

Singleplayer or Multiplayer
Works on any render distance

Foss currently features:

10 Unique Bosses to fight, each with their unique skills
10 Boss Merchants to buy custom gear from
8 Custom Boss Dimensions just to fight bosses
Inventory Charms - Custom items that grant you custom buffs from anywhere in your inventory!
Armor Set Bonuses - Get special effects whenever wearing all 4 pieces of an armor set!
Special Items - Infinite throwable potions, bows with piercing arrows, you name it!
Merchant Dialogues and a bit of lore, if you're into that!

Planned Features ("Coming Soon" - or not):

Another 4-10 bosses, dimensions, merchants, armor sets, weapons and charms
~~Minecraft 1.17.1/1.18.1 support (currently untested)~~ probably cancelled
"Final" boss fight

Notes:

End Dimension might look significantly better on Iris 1.2.2, as it is no longer broken like on OptiFine. Iris is now recommended for this map.
Resource packs used on the screenshots and video (not sponsored): Zinkenite Mobs, FreshAnimations, VanillaTweaks, Shield Corrections, NewDefault+, Programmer Art
Shaderpack used: Complementary shaders (highly recommended. Also recommended to set Vanilla Color Influence in water settings to 100% to be able to see custom water colors!)
If using NewDefault+, custom water/sky colors will be broken.
If your grass color looks weird, try pressing F3+A

Special Thanks:
