Tactics
They hit regularly, but fairly weakly. As a result you may run out of food quickly. Full Guthan is useful to negate this. Wear armour that has a good magic defence such as dragonhide or splitbark. You can also pick up bones from other monsters and use the Bones to peaches spell to give you extra food. After The tale of the Muspah quest, you will be able to freely access the caves to the north which are home to many jellies, the cave is an area when many people can be, but never see each other meaning you will always be able to kill the jellies there without any competition.
