+5 Mithril Twilight Full Plate of Lesser False Life

[Lux-Aeterna]

This is rr Elf/Drow umd 24 lvl 14 req.
15% Arcane Spell Failure

This item is probably for trade. What can I expect for it?

I'm hoping for +2 tomes and large ingredients.

I know it is very valuable but I'm not sure exactly how valuable (i.e. wop rapier value).

Thanks
