Is Bastiodon Good in Omega Ruby & Alpha Sapphire Playthrough?

Rock/Steel from the Shieldon fossil with 168 Defense. AbilitySturdy keeps it alive against one big hit. 4x weak to both Fighting and Ground, so keep it away from Brawly and any Earthquake user. A fortress against everything else.

Bastiodon Weakness

Bastiodon's Rock/Steel typing leaves it vulnerable to Fighting, Ground, and Water. Fighting and Ground hits land at 4x, so they're the biggest threat. It shrugs off Poison-type attacks completely. 8 resistances give it solid defensive coverage on top of that. Bastiodon's physical bulk (base 168 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

ORAS Bastiodon Best Moveset

Rock/Steel at 168 Defense and 138 Sp. Def. AbilitySturdy survives one hit from full HP. But 4x Fighting and Ground weaknesses mean the two most common physical types hit super-effectively. The moveset absorbs neutral hits but crumbles to the types it sees most.

Pokedex Entry

When they lined up side by side, no foe could break through. They shielded their young in that way.

Any frontal attack is repulsed. It is a docile Pokémon that feeds on grass and berries.

Bastiodon Omega Ruby & Alpha Sapphire Guide

  • In Omega Ruby & Alpha Sapphire, Bastiodon has a 495 base stat total and ranks as C-Tier: a niche pick in Omega Ruby & Alpha Sapphire's meta. It works best as a support. Stealth Rock with Leftovers is the standard set.

  • In Omega Ruby & Alpha Sapphire, watch for Lucario (Fighting), Garchomp (Ground), and Milotic (Water) when using Bastiodon. They all hit it super-effectively with STAB. Lucario is the most dangerous since Fighting moves deal 4x damage. At base 30 Speed, Bastiodon won't outrun any of these threats so switching to a resist is usually the safer play.

  • Sturdy prevents being KOed from full HP, leaving 1 HP instead. That's the one you want on Bastiodon. Soundproof is the hidden ability. Niche, but it has its uses.

  • In Omega Ruby & Alpha Sapphire, Bastiodon fills the support role. It's a physical attacker with base 52 Attack. Base 30 Speed is low. Priority moves or Trick Room are the way to go. And it's tanky enough to absorb a few hits.

  • In Omega Ruby & Alpha Sapphire, run Stealth Rock, Toxic, Taunt, and Metalburst on Bastiodon. Stealth Rock is the most common pick at 0% usage. This set covers the support role with a mix of damage and utility.

Game Availability

Bastiodon first appeared in Diamond & Pearl and has been available in 12 games across 7 generations. Obtainable through wild encounters in most titles where it appears.
