Hazelia is something I've been working on from time to time for the past 6 months and I'm finally in a spot where I believe it to be done!
In this mod you will find a couple more ores, 7 mobs, 9 structures, and decent number of blocks including 2 different wood types!
This mod also comes with special weapons, like a sword you can make out of condensed emerald blocks, or a scythe that shoots projectiles! (The scythe comes with an infinity enchantment, it can be found in a large structure in the domanian biome in the special dimension.)
Info:
The boss can be found in the Domanian biome underground, somewhere between Y= -55 / 0. To summon the boss you will need to right click the altar with the "Heart Of Hazath" which can be crafted, but will be consumed on use. All of the other crafting recipes such as the weapons should be in the recipe book, and will unlock once you get the main ore/resource for each weapon.
