ROCK is created when LAVA or molten STNE is placed under more than 30 pressure. This produces molten ROCK. (To prevent loops, this transition will not happen if the LAVA is below 1943.15C and above 120.0 pressure)


ROCK can be used as a solid foundation for CNCT. Contrary to all other elements, CNCT will not fall of an edge of ROCK. ROCK also has a strong resistance to both ACID and DEST, making it a good material in bunkers.


While solid, ROCK can be eroded with water. Water with a velocity around .5 or greater has a small (1/1000) chance to erode ROCK into SAND (33%) or STNE (67%).

Molten ROCK

Most of ROCK's reactions are done on molten ROCK.

Molten ROCK under at least 25 pressure has a 1 in 12500 chance to turn into molten versions of the following:
25 - 50 pressure:

CNCT.png (50%)

50 - 73 pressure:

73 - 75 pressure:

75 - 100 pressure, >= 4726.85C:

100+ pressure, >= 4726.85C, additional 20% chance:
