Envy in Aura Monster Simulator on Roblox appears to be tied to an aura-style buff, but I couldn’t verify a game-specific effect from the available information. The safest answer is that it likely affects your aura power or aura-related performance, not a direct combat stat.

What I could confirm

  • The Roblox game page for Aura Monster Simulator says you climb to gain Aura and use it to upgrade climbing skills.
  • Search results for “Envy” mostly pointed to unrelated games or general “aura” concepts, not a clear Aura Monster Simulator wiki or update note.

Practical take

  • In games like this, a named aura such as Envy usually acts as a special modifier, cosmetic aura, or bonus effect rather than a standalone weapon.
  • If you saw Envy in-game, it is most likely connected to progression, rarity, or a temporary boost.

TL;DR

Envy seems to be an aura-related feature in Aura Monster Simulator, but I can’t confirm its exact in-game effect from the sources available.
