Ice strykewyrm

The Ice strykewyrm is a slayer monster that requires a Slayer level of 93 to kill. It is located near the Muspah cave. It has the unique drop of a Staff of Light. To deal damage to it, a Fire cape must be worn.

The slayer master Kuradel can assign you these, However if you don't own a Fire Cape she will not assign this task to you.
