King's Grade, made from Amn, Ral, and Thul, in that order. This works in 3-socket Swords and Scepters only. Possible in v1.08 and above.
Lots of nice mods on this one, but nothing overwhelming. A well-rounded weapon, better against undead and demons than normal monsters. The 150% damage to Demons is present on swords as well as blunt weapons.
