About Onyx

The Onyx is a members-only skilling resource in Old School RuneScape.

"This looks valuable"

Over the last 30 days it traded between 2,632,172 and 2,939,647 gp on the Grand Exchange, averaging 2,773,881 gp. About 162 units changed hands per day. The price is down 3.2% across that window. The Grand Exchange buy limit is 11,000 every 4 hours. Selling one at the average price costs 55,477 gp in Grand Exchange tax.

Casting High Level Alchemy returns 120,000 gp, which is 95.7% below the 30-day average price, so alching a bought one loses money.
