Mobile - 0.75

Another expense is necessary for strongholds magically designed to be mobile or capable of extraplanar travel. The most fantastic of strongholds, these incredible creations can take flight into the skies, sail across the seas, submerge below the oceans, or even tunnel down into the hard earth. Of course, such wonders are exceedingly rare, and with good reason. They don’t come cheap.

Much like the augmentations listed above, the cost for mobile strongholds depends on the size of the stronghold (in spaces). Table 2–12: Stronghold Locomotion and Table 2–13: Stronghold Mobility list a cost per stronghold space for the function selected.

In addition, you can build your stronghold so that it can move in nonstandard methods, including teleportation and planar travel. See Table 2–14: Stronghold Planar Mobility for the cost (also per stronghold space).

You can tie your stronghold’s mobility to a single object within the stronghold (which may be activated by anyone touching the object and uttering a command word), a location within the stronghold (which may be activated by anyone standing within the location and uttering a command word) or to a single creature within the stronghold (who can activate the movement from anywhere within the stronghold with a command word).

You can’t use Search to discover a stronghold’s mobility functions, nor will Disable Device have any effect on a stronghold’s mobility. Dispel magic or Mordenkainen’s disjunction must affect or be cast separately on each space of the mobile stronghold to lose its mobility.
