Highlights

Separate race and class choices allow elves to combine spellcasting with fighting or thieving. Encounter reactions and morale let negotiation or retreat resolve threats without fighting to the death. Dungeon stocking and wilderness encounter tables help the GM prepare expeditions.

Considerations

Characters normally die at zero hit points unless the GM adopts an optional survival rule. Racial ability requirements and class restrictions limit character combinations. Casting can be interrupted by an attack on the same initiative count even if it misses.
