I need help. My Shedninja was battling a Gible, and it fainted AFTER the turn that the Gible use Sandstorm?
If you want it to be immune to weather damage you can make your Shedinja hold Safety Goggles.
yes, shedinja isn't immune to passive damage like sand, hail and status conditions like burn or poison and it will faint even on stealth rocks, spikes and leech seed
