After completing the quest  , he can provide any of number of random hexes, which most often get you turned into a critter (you can dispel this by right mouse clicking the buff). Sometimes his hexes produce cool effects such as being drunk, ghostly, getting thrown into the air (make sure you have a full health bar for this as the "feather" effect, when you fall back down, can trigger too late on rare occasions and you will fall to your death), or becoming enlarged for 5 minutes (very funny when you add other effects such as bloodlust and a "bug" from the gnomish engineering trinket Gnomish Poultryizer). Strangely enough, he is one of the only, if not the only, Trolls in World of Warcraft with his speech set.
It is worth noting he has the same voiceset as the Warcraft 3 Witch doctors.
Bom'bay's name is a play on Doctor Bombay from the classic TV sitcom Bewitched. Doctor Bombay was doctor to a family of witches, and was in fact a warlock himself.
- Patch 1.5.0 (2005-06-07): The Grow effect that Bom'bay in Sen'jin Village would sometimes cast on characters was reduced from 100% to 50% growth.
