Drome

Dromes are immobile trading platforms located on the surface of desert and rocky planets, they cannot be found on the Snowy planets. (Presumably because the inhabitants are too hostile for friendlies to set up shop.) It has a large shield capable of surviving multiple bomb explosions in a row, and 400 health on top of that. However it is possible to destroy a Drome with enough time and patience.

You can exhaust a Drome's item supply, but after a time the shop will restock.
