Looking for some help
 

Hey guys I was wondering how I can acquire a Crystal key, and im also curious to the location of bosses such as Elstan and Larrisa? if someone can please let me know id greatly appreciate it. Im also curious with the function of the Grey Crystal?

There is no boss with the name "Elstan" or "Larrisa".
Crystal key is when you combine the two different crystals you get from specific slayer task monsters. If you do not have the crystals already, you are more likely to get a task that can drop the crystal.

im curious to know why "Elstan" and "Larrisa" is on the drop list? and thank you very much for the reply.

Test npc's from when I made a command.

oh okay I understand, so there is no way of obtaining decorative armor?
