Some features are nice, like the protein craving giving strength, the effects could've be more ring based (also morning hunger is a bit much), and stone/deepslate dropping iron — love that, actually I created a datapack to drop random items from random blocks, you can check it out! Ghast tweaks are also good, more damage but not too much and more ghast tears. Copper blocks for beacons? Also with oxidizing and waxing? Perfect, wish Mojang did that.
But some changes feel overpowered or unnecessary: torch and campfire recipes, shield ( yeah it could have been changed slightly but iron block is a lot), well I am not fun of armor/mob modifiers but it's your work so I respect that. When it comes to changes to recipes I also have datapack for that and since torches are usually very easily used I changed recipe for them to 1 stick + 1 coal = 8 torches. There are some other limiting or restrictive recipes such as bookshelves only from nether wood or cobweb requiring slime, when it's just web
Anyways, very good job at making Minecraft more unique and rpg based!

accidently installed this on my paper server, the dev diary never popped up. How can I safely uninstall this pls :)?

and what are the aurmor buffs
(i am speaking to figure out compatability with other datapacks, so i would useualy look on the wiki, but i need technichal stuff)

does it contain new tool types or have any new ores

does this datapack affect mobs health or it just reduce your overall damage? since increasing mobs health will change some of the mobs farm

Update to 1.21?
