Parslay

Parslay is a herb used in the Dungeoneering poltergeist puzzle. It is one of the dangerous herbs. It can be consecrated using a certain Herblore level to make a consecrated herb.

If it is not the appropriate herb for the puzzle and you try to pick it, you get injured for a small amount of damage as "The herb cuts into your palm and checks its enchanted gem", as a small nod to the Slayer skill.

Trivia

 * Parslay's name is a pun on the real-world spice.
