This system ignores the Development Points (DP) section of BBF and makes an attempt to use a variant of the Labyrinth Lord XP system.
XP is divided evenly among the party. To determine the total XP award per encounter use the following guidelines.
Treasure 1gp = 1xp
Creatures (BP x rank) + (abilities x rank) = xp
Major NPC (BP x rank) + (sum of skill levels x rank) = xp
Minor NPC Minor NPC Score/10= xp
Example: The party fights a basilisk whose lair contains a 100gp gem and 34gp coins. 134 for gold and 90 for creature = 224XP
Example: Major NPC Kalak (Rank 3 wizard) from Soul's Reach modules = 87XP
Example: Minor NPC 4 Human Thugs 55% = 22xp
GM's can also award XP for good role-playing, making the GM laugh, etc.
