A Jelly is a Slayer monster that requires level 52 Slayer to kill. It can drop the rare Absorption boots and Grounding boots, which give very high magic defence bonuses. They are found in Abandoned 1 floors and up. As of 19 April, 2012, Slayer monster frequency in Dungeons has been increased by nearly double, making an encounter with Jellies a far more common occurrence on attempted floors than they previously were. Players often report encountering four or more Jellies in one room.
