* You can erupt stone tiles that are fully submerged in water.
* Cannot erupt on non-allied deed. When trying, you will see the message: {{event|inline|Some psychological issue stops you from spawning lava here.}}
* An erupted tile's northwest corner will might become slightly raised. Usually by 4 slopes.
* Erupt cannot be used on a tile next to a cave entrance, above an empty mine tile, or above a reinforced mine wall. Trying to do so will initially tell you "You start concentrating on the rock.", but end up with "Nothing happens" - and this will not consume your daily usage of Erupt
* Nearby items such as altars and vehicles may prevent Erupt from working.
