This mod is a remake/remaster of an old 1.6.4 mod, and I've decided to bring it back, staying as faithful to the original as possible, while also adding a few new things

AngryMobs Mod - 9Minecraft.Net

It has both an English and Spanish translation, in addition to requiring the Curios Mod

Adds 4 new aggressive entities that spawn at night, if they don't burn during the day. They can also kill other mobs like cows, chickens, pigs, etc.

There's even a small chance that killing a pig will cause the Headless Pig to attack you

Killing these angry mobs has a small chance of them dropping a new material/gem

"Fragment of Anger" can also be used to create a block of anger, making it easier to store

With these anger fragments, you can create a Netherite and Enraged Iron Ingot upgrade, we can craft the "Anger Upgrade" which will be very useful to create weapons and armor better than Netherite, in addition to a medallion/necklace

For the Angry Heart Medallion you must first craft the Iron Medallion, which by itself when equipped will give you Resistance 2

With the iron medallion, a fragment of anger, and the anger update we can craft the angry heart medallion on the Smithing Table, which will give resistance 4 and regeneration when equipped.

Likewise, with Anger Shards and the Anger Update, you can make Anger armor and tools, a direct upgrade to Netherite armor

Enraged Iron Ingots are obtained by killing the Mad Iron Golem, which is summoned with two Anger Shard Blocks and a Pumpkin.

Basically a mini-boss

And finally, as an extra, you can also use the ingots of furious iron to create the Apple of Fury, both its normal version and its enchanted version.
