Location: Route 111’s Mirage Tower (post-6th gym).
Lost Artifact: A cracked wall on the 2nd floor—only visible if you have a Pokémon with Flash in your party. Use Strength on it.
Reward: Fossil of the Ancients – revives into Armaldo but with a custom ability: Prism Armor (reduces super-effective damage by 50%).
Why best: This Armaldo is not in any wiki. It’s a tank that laughs at Fighting, Rock, and Water moves.
Simply having the artifacts isn't enough. You need synergy. Here is the "Hall of Fame" team used to beat the Hyper Emerald 55 final superboss, "Shadow Deoxys": pokemon hyper emerald 55 lost artifacts best
The Shattered Mirror is a held artifact that grants the user immunity to their own primary type’s weaknesses but doubles damage from their resistances. For example, a Water-type holding it would take zero damage from Grass and Electric moves but double damage from Fire and Ice moves. This risk-reward item is best used on Pokémon with few weaknesses or those that can eliminate their counters quickly. Location: Route 111’s Mirage Tower (post-6th gym)
Its best application is on Steel-types like Aggron or Mega Metagross, which normally fear Fire, Fighting, and Ground moves. With the Shattered Mirror, they lose those three weaknesses entirely. The doubled damage from their resistances (e.g., Grass, Rock) is negligible because those moves are rare in competitive sets. Thus, the Shattered Mirror creates near-invincible walls. In a hack where enemy coverage moves are everywhere, nullifying three common weaknesses is a god-tier advantage. It ranks second only because it requires careful team building, whereas the Chrono Amulet fits almost any slow team. Reward: Fossil of the Ancients – revives into
