The Complete Dungeons & Dragons 4th Edition Player's Handbook
Does the prospect of rolling a pair of eighty-sided dice while crunching complex calculations to keep track of Hit Points and Fatigue Bumps frighten you? Worry not! Combat in D&D has been completely overhauled.
When an enemy (dragon, the only enemy type in D&D) is spotted, all Carloses will confer. If at least one Carlos decides that the enemy should die, it will be vanquished. No experience is rewarded for defeating monsters, as no Carloses will gain experience after reaching the maximum level (1).
