Algarum thread detail

Algarum thread is used along with sirenic scales to make sirenic armour. It can be bought from Ocellus Virius, the Bandit general store in the Wilderness, or on the Grand Exchange. Three of these are needed to make a sirenic hauberk, two to make sirenic chaps, and one to make a sirenic mask.

The shop interface to buy these from Ocellus cannot be opened without at least 500,000 in the money pouch or inventory.
