Tormenta Arena

Changes the weather to a sandstorm for five turns. Pokémon that are not Ground, Rock, or Steel take 1/16 their max HP at the end of every turn. Every Rock Pokémon’s original Special Defense is raised by 50% for the duration of this effect. Solar Beam’s power is halved. Moonlight, Morning Sun, and Synthesis only heal 1/4 the user’s max HP.
