Pandemonium Scale

A  (Japanese: パンデモニウムスケール Pandemoniumu Sukēru, abbreviated スケール in ), is a property possessed by Pandemonium Monsters. When performing a Pandemonium Summon, the Pandemonium Scales listed on the Pandemonium Monster are used to determine the range of Levels that can be Pandemonium Summoned.

On either side of each Pandemonium Monster, there are two diamonds: one green, the other yellow, with two numbers next to each. These numbers values are always different, and different by a range of at least 2.

Mechanics
Once per turn, if a player controls a face-up Pandemonium Monster in your Pandemonium Zone, they can perform a Pandemonium Summon. A Pandemonium Summon allows the player to Special Summon any number of monsters from your hand or face-up Extra Deck whose Levels all between the Scales of the Pandemonium Monster in your Pandemonium Zone. Afterwards, the monster in the Pandemonium Zone is destroyed. This destruction is not treated as being by a card effect, and would thus not trigger effects that activate upon destruction via card effect.
