You get the "Erupt" option on rock and [[cliff]] tiles. The tile is transformed into a lava tile. Can't be used on a tile too close (less than 2 tiles) to a Magranon [[altar]]. Timer: 40 seconds.
* Northwest corner of lava tile will rise by 4 slope after erupt.
*Cave walls that are under the tile that is erupted will change into lava walls. This includes ore veins. These lava walls can be changed into regular cave walls with the freeze ability.
