Crunching Numbers on out stronghold.<br/><br/>Wall of Iron is a spell only on the Sor/Wiz spell list (Level 6)<br/><br/>It has the same dimensions as wall of stone so at my caster level I can get us a 50% discount per stronghold space by casting it 11 times per stronghold space. Thats 440 walls of iron for a 40.<br/><br/>So assuming a stronghold of 40 spaces pure iron walls will cost us 84,000 assuming I cast wall of iron 440 times.<br/><br/>If we do exterior iron walls and interior stone walls I can planar bind something to cast the walls of stone (A Dao can use wall of stone unlimited times per day. Meaning the whole thing is just a few hours of work for it).<br/><br/>This would end up costing 42,000 for for the stronghold before we buy components. Unfortunately I still have to cast wall of iron 220 times, not quite sure how I'm going to wing that one.. Assuming we can get some trees hauled over we even have the pretty wooden veneers free.<br/><br/>If we can simply buy the materials for the stronghold components and I'll lyre them together so all stronghold components are purchased at 70% value.  This is assuming we can transport everything through our own power. If we have to use others we end up forking out more coin for "exotic" location. 15% more to be precise.<br/><br/>Know any outsiders of 12 hd or less that has wizard spellcasting (6th level spells) or can use wall of iron as a SLA? If we just buy the iron rather then have me make it up with magic it costs 84k, or 168k if we don't use stone at all.<br/><br/>And that gets us an unfurnished stronghold of 40 spaces.
