Dangerous Mobs
by SuRapunzel
Dangerous Mobs adds hostile mobs to the Overworld, Nether and End, along with bosses, drops and equipment that suit a more demanding game.
What it does
Several new hostile mobs spawn naturally in the world, including mobs that appear on the surface and others that emerge from caves. Some of them are destructive, and a few are labeled as bosses and show health bars. Upgraded versions of those bosses can be summoned through a ritual, and an option enables them.
Defeating these mobs yields valuable drops. Stronger mobs give better rewards, and the drops include equipment, food, blocks and crafting ingredients. Iron equipment is needed before venturing into deepslate, where the harder threats are. The mod ships light elements meant to add suspense. Its assets are adapted from Minecraft's own.
The mod is published for NeoForge only, with builds for 1.21.1. Every player and the server need a copy of the mod. It is released under the MIT License but is not open source.

How it compares
Otherplaces is a NeoForge mod for 1.21.1 with the same client and server environment, under All rights reserved and not open source. Liyam's Mod targets 1.21.8 on NeoForge, also client and server and closed-source. No Aggressive Mobs runs on 1.21.4 and works with either side or both, so it reduces aggression rather than adding dangerous mobs.
