It's been a while! Etherium is finally out and is being constantly worked on! I'm making sure many bugs are fixed and all items aren't too overpowered. Soon, the mod will have all it's main bugs fixed and will be adjusted to perfection! Sorry for the inactivity!
The Cataclysm Mod has now been replaced by The Etherium Mod, so if you can't find it on the mod browser, that's why! Also, The Etherium Mod is not out yet, and still needs some little bugs fixed, and some tweaks to things.
