Ad Astra: Extra Additions
Ad Astra: Extra Additions is an addon mod to the majorly popular Ad Astra mod by AlexNijjar, obviously because of this Ad Astra is a required dependency so ensure you have that installed already.

Modrinth version has better description.
Currently this mod is my first dip into mod development, so only features a full expansion to Ostrum ore in Ad Astra; adding Ostrum tools and armor - it also implements an end-game armor known as Deshtrum which is made using Ostrum, Desh and Netherite to forge Deshtrum Ingots which can then be melted down into Melded Deshtrum Plate for armor. It also adds several high definition paintings to the painting pool in the 32x32 format.
Ostrum Items can be crafted out of Ostrum Plate which can be made from Ostrum Ore >> Ostrum Ingot >> Ostrum Plates
