You Keep what you Kill

Experience from Treasure
Cribbed from B/X D&D, treasure recovered from dungeons also counts as experience on a 1gp = 1xp ratio. This also includes treasure given by NPCs as payment or a reward.
Shields shall be Splintered
From Trollsmyth. As well as adding +1 to AC, shields can be used to absorb all damage from a single, non-suprising hit. A shield used in this way is destroyed and must be discarded.
