Arena: Room of Inversion [
Source]
Field Type: All Types
Complexity: Simple
Format: All Formats
Restrictions: None.
Description:
Built as a mirror to the more popular "ASB Arena," the Room of Inversion was eventually covered by a dome for trainers in the rainy season who did not want to fight under the rain. However, as battling while taking the elements in stride became more and more common, the Room of Inversion became increasingly desolate and out of use. Then, one day, the Room went through massive renovation; when it was finished, a strange device had been placed in the center of the arena—nobody knew what it did, until the first battle there was fought.
The strange device, known as the "Inverter," transforms all of the Pokemon's weaknesses into resistances and resistances into weaknesses. That is, 4x weaknesses become 4x resistances, 2x resistances become 2x weaknesses, etc.; however, immunities, for some strange reason, remain immunities. Resistances and weaknesses gained or exacerbated through abilities are not affected by the Inverter; their effects apply after the Pokemon's natural resistances are swapped.
However, the Inverter is not indestructible... during the battle, it may be attacked as part of a multi-target attack or as the target of a single-target attack; all attacks that "hit all adjacent Pokemon" will automatically hit the Inverter. The Inverter has 50 HP, 4 Def, and 4 SpD, as well as a 2x resistance (not inverted) to all types of attacks. Once the Inverter is destroyed, the inversion effect will immediately disappear.
Summary: Weaknesses swapped with resistances.
