Stamina raises the Pokémon’s Defense by +1 stage every time it takes direct damage from an attack. Each hit that lands stacks another +1. With enough hits absorbed, the Pokémon becomes extremely difficult to knock out physically.
The stages follow the normal boost system: +1 is 1.5× Defense, +2 is 2.0×, and so on up to the +6 cap.
Archaludon in rain
Archaludon is the primary Stamina user in Reg M-A. It slots into rain teams alongside Basculegion and Pelipper, where it fills a specific role: taking physical hits that rain teams are typically weak to while stacking Defense boosts and threatening back.
The synergy is deliberate. Rain teams often face aggressive physical attackers trying to remove Archaludon or Basculegion before they sweep. Every time the opponent attacks Archaludon, it gets tankier. After 2–3 hits, physical moves barely dent it — and Archaludon is still threatening with Thunder (100% accurate in rain) and Dragon-type attacks.
What stops Stamina
- Special attacks don’t trigger Stamina at all — the ability only activates on direct physical damage. Special attackers can ignore Stamina stacks entirely.
- Clear Smog resets all stat stages, clearing every Stamina stack Archaludon has accumulated.
- KO immediately — if the opponent can knock it out in one hit before Stamina stacks, the ability never matters. The window is in turns 2 and beyond.
Spread move interaction
In doubles, spread moves hit twice per turn (once per target). If Archaludon is hit by a spread move, it gains Stamina from that hit — but then the move hits the partner too (if grounded), not Archaludon again. One activation per turn from spread moves, not two.
