Grimoire of Gaia
by Mrbysco
Grimoire of Gaia adds monsters and mobs to Minecraft Java Edition, aimed at players who want the game to stay a challenge.
What it does
The mod adds new hostile mobs and monsters that make the game harder, and it is meant to keep survival play demanding for experienced players. The author describes it as a challenge mod rather than a source of new gear, so enhanced AI and equipment are left to other mods.
Grimoire of Gaia is not beginner friendly, and the author recommends it for experienced players or for later in a play session. Client and server both need the mod, and the files are published for Forge, NeoForge and ModLoader across 18 release versions, 1.2.5 – 26.2. The code is not open source; the mod is licensed as All rights reserved.

What the author says
My intention with this mod was to make Minecraft remain a challenge and to give it a more unique experience. Because I lack the skill in programming enhanced AI or equipment, I intended for this mod to add mobs and make the game harder while more powerful and well coded mods provide high-end enhancements to the player.
