In-Game Description

A tiny bug that produced light.
Brightbugs are said to comfort the dead,
and are found in the marshlands leading to the Undead Crypt.

By ingesting a brightbug just before death,
the moment at which they glow most brightly,
one attains great power for a short time.
Often utilized as a last-resort for adventurers who have lost their way.

Has no effect in other worlds or for phantoms.


  • +20% damage and -20% incoming damage for two minutes.
  • Cannot be used as a phantom or while White or Gold phantoms are present in the host's world. Cannot be used once invaded by a Red phantom, unknown if effect would persist if used before an invasion (need confirmation on Grey/Blue) .
