A jubster is created by a player using a raw lobster and a raw jubbly on the jubster Altar of Life in the dungeon and then activating the altar found in the east part of the dungeon. The Homunculus in the dungeon then creates the monster, which appears near the altar and will attack the player.
If players wish to obtain raw jubbly, it is advised to kill these if they have a high combat. The jubster will always drop raw jubbly in small amounts. It is much easier than baiting and waiting for a jubbly to arrive.
