About Supercompost
The Supercompost is a members-only skilling resource in Old School RuneScape.
"Super-good for the smallest or largest of plants"
Over the last 30 days it traded between 16 and 31 gp on the Grand Exchange, averaging 23 gp. About 1,012,487 units changed hands per day. The price is up 29.2% across that window. The Grand Exchange buy limit is 2,000 every 4 hours.
Casting High Level Alchemy returns 51 gp, which is 121.7% above the 30-day average price, so buying and alching it covers its own cost before the nature rune.
