Karma (3.5e Other)
From D&D Wiki
Karma is an optional additional game mechanic that a Dungeon Master may choose to include within his or her game.
A karma point is awarded at the Dungeon Master's digression to a player for some action that the dungeon master deems worthy. A player may spend karma points to help turn situations more favorable. Once spent, a karma point is lost forever; thus the player must earn more in order to reap more benefits.
 Earning Karma
Though each Dungeon Master may vary on their ideas of what is and is not worthy of Karma, some basics tend to be used. These include the following:
- In-Game Earning
- Completing a difficult task or mission; Clever ingenuity on the player's part to solve a problem; Sacrifice for other's sake; Great Roleplaying
- Out-of-Game Earning
- Not Meta-gaming even when it makes life harder on a character; attendance; good attitude; hosting or providing food
 Spending Karma
Every Dungeon Master may differ on what they allow Karma points to be spent on, and will usually provide a basic rundown when informing his or her player's that the system will be used. Some basics include:
- To get a re-roll of a die; to add to a skill check; to get one more action in a round; to add one point to an attack or damage roll
