Dragonscale Bo Staff

ITEM 6
Price 240 gp
Usage held in 2 hands
Bulk 2
Category martial
Group club
Damage 1d8 bludgeoning

This +1 striking bo staff is covered in scales shed by or harvested from a dragon. When benefiting from the circumstance bonus to AC granted by the bo staff's parry trait, you also gain a +1 circumstance bonus to saving throws against magical effects of the tradition matching the dragon who provided the scales, plus resistance 5 to a damage type determined by that tradition: force for arcane, spirit for divine, mental for occult, or fire for primal. For instance, a dragonscale bo staff made with scales taken from an omen dragon would provide a +1 circumstance bonus to saves against occult effects and resistance 5 to mental damage.


Craft Requirements The initial raw materials must include scales from one type of dragon.
