Q97:
How can I get the crit range on a Minotaur Great hammer up? (19-20/x4 crit) All I can think if is making it an impact weapon.
(No BoVD)
A97: If you're not set on bludgeoning damage, get a Kukri (18-20/x2) with Kaorti Resin (makes it x4). The Resin ends up costing 3850*, bringing the total cost of a masterwork kukri made with it to 4158.
*25 x the XP cost, which is half of the masterwork kukri cost (308 -> 154), so 3850.
Also, Weapon Master, Psychic Weapon Master, and Disciple of Dispater are all PrCs that fit the bill for expanding critical threat ranged.
The feat Instinctive Consummator is great for instant confirmation.
