Reactive Combat in Practice

The system is most reactive for characters with high Reflex saves. Having the highest Reflex save is analogous to being in the dealer position in Texas Hold'em poker, allowing you to react to others' actions. Example scenario: Two mages are fighting. Mage A has a Reflex save of 1d20+15, Mage B has 1d20+16.

Mage A announces casting Fireball on Mage B. Mage B declares casting Stone Wall for protection. Both roll Reflex saves: Mage A gets 20, Mage B gets 19. The GM rules that the Stone Wall comes up too late, and the Fireball deals damage to Mage B.
