Adventures In Eberron
Players Roll All The Dice
These rules put the spotlight on the player characters and reduce the randomness of player-character deaths. In large combats, players often have little control over the outcome of events when it isn’t their turn.
Whenever a GM would roll a d20 for a monster opposing a PC, use a result of 12, remembering that
players rolls a d20 and win ties.
Attacking and Defending PCs make their attacks just like they do in the standard rules. Their opponents, however, do not. Each time an enemy attacks a PC, the character’s player rolls a defense check. If that defense check equals or exceeds the attack score of the enemy, the attack misses.
To determine a creature’s attack score, add 12 to the creature’s standard attack modifier.
