The Max Mushroom in Roria Conquest appears to be a healing item, but I couldn’t verify the exact in-game effect from the available information. Based on how “Max Mushroom” items usually work in similar games, it likely fully restores HP or gives a major heal.

What it likely does

  • Restores a character’s HP to full, or very close to full.
  • In some games with the same item name, it can also boost battle performance or stat effects, but that depends on the specific game.

Important note

The search results I found did not show a clear, direct description for Roria Conquest itself, so I can’t confirm the exact effect with confidence.

Best guess

If you’re seeing it as an item in Roria Conquest , the safest assumption is that it is a strong recovery item rather than something used for crafting or progression.

TL;DR: It most likely heals a party member or Pokémon-like unit to full HP , but I couldn’t verify the exact Roria Conquest-specific function.
