All of these ingredients can be purchased at Funch's Fine Groceries. A premade blurb' sp (Premade blurberry special) can be purchased at the Blurberry Bar for 30 coins. An alternative for players who need a Blurberry special for Death Plateau is to buy a Premade Blurberry Special from the Gnome barman at the first floor on the eastside of the Grand Tree, provided he has some in stock.
It heals 6 HP, increase strength by 6, and reduces attack by 4.
Contrary to popular belief, the premade Blurberry special will work for the Death Plateau quest.
When taking the Gnome glider to Gandius, there is a Premade blurb' sp that spawns on a table nearby the landing site.
