Robes of Xin-Shalast
Silken Robes of Arcane Might
Woven of the finest of silks and accented with precious gemstones and gold, the robes are surprisingly light and easy to move in.
They grant a +6 armor bonus and spell resistance 24, but also cause the wearer to cast all spells at +1 caster level.
Two of the robe’s pockets function as handy haversacks. The wearer of these robes can exist comfortably in all high altitudes, including within the death zone at altitudes of 26,000 feet and higher.
