Q 102 Looking for a source. Does anyone know where Lesserbane and Greaterbane are from?
Greaterbane: A greaterbane weapon has all of the properties of a lesserbane weapon, plus it bypasses the damage reduction of the designated creature as if its enhancement bonus were a +4 more than its actual value (this modified enhancement bonus can exceed the normal +5 limit of magic weapons).
A lesserbane weapon can be crafted into a greaterbane weapon as if adding another +1 ability. For example, a +1 lesserbane longsword (8,315 gp, cost to create 4,315 gp + 320 XP) could be made into a +1 greaterbane longsword (18,315 gp, cost to create 9,315 gp + 720 XP) for a cost of 5,000 gp and 320 XP (the difference between the cost to create of the two weapons).
Caster Level: 8th; Prerequisites: Craft Magic Arms and Armor, summon monster I; Market Price: +2 bonus.
