What Is an Acquired Immunity?

Reflex saves are DND (or writing D & D) rules based on the agility bonus against the immunity of the corresponding authority or spell. When a character tries to dodge a fireball or avoid annoying cobwebs, a reflection check is required. Reflex saving represents the result of a character's maneuver. As its name suggests (Reflex), this is a saving attribute related to the character's reaction ability, so its key attribute is Dexterity.
