Overall, this Mod is quite complex in its looting system but once you get the hang of it, your game will become way more interesting. Furthermore, you can also collect different gems throughout the journey, to strengthen your items suffixes and affixes (Items’ Bonus Attributes).
Upon defeating them, you’ll be rewarded with great treasury, which might contains some of the best items in the game, thus help your character progress easier.
In general, you’ll have to fight against unique monsters with their own elements instead of the bland original system of Minecraft. The game is known to have one of the best looting system, hence the port over for Minecraft.
