These are pages that cause players to call, ignore, or otherwise interact with the combat call "Reflect".
Reflect is one of the few defensive combat calls in the system. It is the only call that acts both defensively and offensively at the same time. The person with an ability that lets them call reflect is the defender in this scenario and the other person is the attacker.
When an attack that meets the criteria for reflection hits the defending player, that player must look their attacker in the eyes (or in some way make it clear who's attack is being reflected) and as clearly as possible call "reflect". It is then the attacker's responsibility to immediately take the effect of the original attack with the same call that attack had as if that attack hit them in the torso. This then consumes a use of the ability granting reflection.
Should the attacker also have an ability that allows them to reflect that same attack, they then respond with "No Effect". This is because you can't reflect a reflected attack. This consumes a use of the attackers reflection ability.
When a dispel effect hits a character protected with a reflection effect the dispel will consume one charge of the reflection with no further effect. A "No Effect" call must be made whenever an attack successfully hits you but does not inflict damage (or does not take effect in the case of spells) so that the attacker knows-that-you-know the attack successfully hit and so that they know they may need to attack with something different.
