A tiny bug that produces 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.


*Almost if not doubles attack and splits damage received to about half.
*The duration of the effect is 120 seconds, not affected by the Lingering Dragoncrest Ring.
*Does not stack with other self buffs.
*Cannot be used if a phantom is present, even as a host


  • Can be purchased from merchant Hag Melentia (at least in limited quantity)
    • Sells 3 Brightbugs for 6000 souls each, later when all were bought another 3 for 18000 and then for 24000 each (48000 each if none were purchased before all main story bosses are defeated). The shop will restock every time one of the 4 Primal Bonfire bosses are defeated.
  • 1 after the Belfry Gargoyle in the area with the invader
  • Aldia's Keep
  • Old Iron King DLC, Foyer bonfire: After the lifts are activated, take the first lift upwards. Run, or jump straight forward to a ledge with iron bars, under another ledge. You will find a metal chest containing 2 Brightbugs, and a crystal lizard.
  • 2 in an iron chest in Frozen Eleum Loyce in the room with the once frozen mimic.


  • Vendrick may or may not become enraged while using a brightbug
  • Glitches ---- The brightbug's duration seems to reset each time the player saves, and quits his, or her game.

      That's not at all true, no idea where they got that from. It's more like 20% more damage done, 20% less damage taken.

        Tip for anyone doing anything hard at all.

        Stockpile these. Its outrageous how strong even the weakest weapons can become when you use these. I cant believe i didnt use any during my no death no fires run. Seriously its borderline cheating. 8 hit killed a Ruin Sentinel on NG7

          The The prices vary as you process through the game29 Aug 2016 10:56  

          You can buy 1 brightbug for 6000 as soon as you reach FotFG, (later on) 12000, (even more later on) 24000 and finally it caps at 48000. They restock each time the price changes, I've bought them each time and I'm kinda of skeptical if they restock after the price hits 48000 but I'm not 100% sure because I don't really know what causes them to change the prices nor causes them to restock.
