Combat Lore is a regular enhancement that is gained if War kills more Angels than Ulthane when the pair are travelling through Anvil's Ford to The Hollows (this also earns you the achievement/trophy "Who's Counting"). If War fails to do this, the enhancement is later available for purchase from Vulgrim for 1000 souls. It has the following bonuses:
Slotted Bonus
- Boosts weapon experience gained during combat. (How much?)
Passive Bonus
- Boosts War's armor level.
Trivia
- It is the best way to upgrade your weapons since it gives the experience boost without drastically raising your weapon damage, as War's Glory does, making your enemies take more hits giving you more experience.
