Addon: Disastrous Dunes

Disastrous Dunes adds several new blocks to the surface of the Desert and Mesas, heres an image of the reworked surface part of the Desert and Mesa Biomes  

First major change to the desert and mesa aside from its completely new look is the introduction of Sandstorms, these will happen whenever thunderstorms happen in the minecraft world  

Underground Desert/Mesa Chnages

The 2 biomes now have spikes underground, alongside replacing all the stone with their own special stone, it even extends to the Deepslate Layer

STRUCTURES:

this addon only adds 2 new structures and theyre both for the desert, they both have suspicious sand as the loot

now, the mesa doesnt have any structures, however, it does have a cave biome that randomly spawns,

Topaz Caves 

ITEMS:

Theres a new weapon, Claymores, Claymores act similar to sweeping edge from java

Amber Items: Amber is an alternative to diamond except with stronger durability, amber replaces diamonds in the desert/mesa
