Pieces Recovered So Far-
Blade - The blade is indestructible and can still be used (provided that a blacksmith can be found to build a replacement crosspiece). On its own, it still does 2D6+2 damage, and is effective against undead and the supernatural. It can be joined with either the pommel or the crosspiece. Charges up to 150 P.P.E.
Right Gem - Another emerald, of the same size as the one on the left, but faceted, and containing a very small rune. Charges up to 40 P.P.E.
Crosspiece - On its own, it seems to be just a dull piece of gold-colored metal. Anyone who knows about swords will recognize that the open hole is meant to fit the blade of a large sword. The crosspiece can be joined with either the centerpiece, the left gem, or the right gem, in any order. Charges up to 10 P.P.E.
Centerpiece Gem - Another diamond, but not quite as big, also faceted, and also with a (smaller) rune floating inside. Charges up to 75 P.P.E.
Left Gem - An emerald, with a smooth, rounded surface, that seems to contain two runes, one overlaid on top of the other. Charges up to 50 P.P.E.
Pommel Gem - A huge faceted diamond, with an ancient rune clearly glittering inside. It can be charged with up to 100 P.P.E.
