Coalossal Weakness

Coalossal's Rock/Fire typing leaves it vulnerable to Water, Ground, Fighting, and Rock. Water and Ground hits land at 4x, so they're the biggest threat. It resists 7 types, so it can switch into a lot of moves safely. Flash Fire grants an additional Fire immunity, reshaping the matchup chart. Coalossal's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Coalossal Guide

  • Coalossal looks average on paper at 510 BST. But Flash Fire is why it sees play. Build around that and it pulls its weight. C-Tier wall on our tier list.

  • Watch for Urshifu (Water), Landorus (Ground), and Golem (Rock) when using Coalossal. They all hit it super-effectively with STAB. Urshifu is the most dangerous since Water moves deal 4x damage. Fighting-type attackers are also a problem. At base 30 Speed, Coalossal won't outrun any of these threats so switching to a resist is usually the safer play.

  • Coalossal gets Flash Fire, Steam Engine, and Flame Body. But Flash Fire is the one that matters. It's the centerpiece of every viable set. Build around that. On wall sets, Flash Fire pairs with Coalossal's base 120 Defense to absorb physical hits on the switch.

  • Coalossal is a mixed attacker with base 80 Attack and 80 Sp. Atk. Tanky enough to absorb a few hits, too. Speed tells the real story. Base 30 Speed is low. Priority moves or Trick Room are the way to go. Fits the wall role.

  • Run Rapid Spin, Flamethrower, Stealth Rock, and Power Gem on Coalossal. Rapid Spin is the most common pick at 0% usage. Flamethrower provides reliable STAB damage.

Game Availability

Available since Sword & Shield, Coalossal appears in 2 games spanning 3 generations. Beyond its original form, it gained a Gigantamax form in Generation 8.
