The Ancient Weapon Feat has been updated. Instead of requiring the sacrifice of gold and other valuables to increase the enhancement bonus of the weapon, the owner must sacrifice XP. It now fuctions identically to the similar ability granted by the Kensai prestige class, except for the levels at which a bonus may be applied to the weapon.
For the time being, if a character has both Ancient Weapon and levels in Kensai, the abilities stack, allowing a quicker progression to adding bonuses to the weapon (with a maximum effective bonus of +10), or may apply the abilities to two separate weapons (for example, a Samurai with Ancient Weapon may start at 1st level with a masterwork katana, which slowly gains enhancements due to the Ancient Weapon feat, and the ability from the Kensai class can then be applied to his wakazashi).
