Additionals

The Extra mod adds many things from new rock types to special effects!

New Rocks =

This mod adds limestone, limestone slabs and stairs, limestone bricks, limestone brick stairs and slabs, biotite and biotite bricks, dried cement, wet cement, mortar, raw bismuth, and chrysoberyl ore.

limestone can only be found in rivers or oceans and bismuth can only be found under y level 50. chrysoberyl generates in granite clusters only. Also both ores can be made into blocks of their respective ores.

dried and wet cement =

dried cement can be made from 2 clay blocks and 2 limestone blocks. wet cement can be made from putting dried cement and a water bucket in a smithing table. wet cement and two blocks of sand can be made into mortar. Mortar is a blast resistant block that takes a long time to break but can also be pushed by pistons! 

Ores = 

raw bismuth can be made into bismuth which can be brewed into stomach medicine.

chrysoberyl ore drops chrysoberyl which can be used to upgrade stone pickaxes.

OTHER = 

when eating most foods, there is a chance to get a stomach ache. This gives you poison and blindness and makes you unable to move since your stomach hurts so bad. Also you drop any milk buckets when you get the stomach ache since the milk bucket is so slippery! This means stomach medicine is the only way to get rid of the stomach ache.
