A kurask head is a very rare drop from kurasks, which require 70 Slayer to kill. It can be mounted in player-owned houses in the Skill Hall at level 58 Construction. This method is a one-time use, and the head cannot be reclaimed.
If players wish to have the kurask head mounted, it must be taken to the taxidermist in Canifis. She will charge 6,000 coins and turn it into a stuffed kurask head. They can then mount it in their player-owned house using 2 mahogany planks.
