Using a red beryl repeater as an focus component for a spell as it is being cast causes the spell to be cast twice. This causes the spell to take effect twice in the same area or on the same target simultaneously. Any variable characteristics (including attack rolls) or decisions the caster would make about the spell (including target and area), are applied to both spells, with affected creatures receiving all the effects of each spell individually (including getting two saving throws if applicable).
A spell whose effects wouldn’t stack if it was cast twice under normal circumstances will create redundant effects if cast this way. For example, a repeated charm person doesn’t create a more potent or long-lasting effect, but any ally of the target would have to succeed on two dispel attempts in order to free the target from the charm. This does not affect the spell’s other components or vulnerability to counterspelling, so a single successful counterspell negates both instances of a repeated spell.
This otherwise works like a metamagic gem, except that a single red beryl repeater can be used three times before being fully consumed.
