Going to Keldagrim for the first time.

The Blast Furnace provides a great opportunity for players to reap great profits by producing a large volume of adamantite bars (worth 1,904 each), which are coveted by high-level smiths.

Depending on your level of activity, you can produce between 1,400 and 2,300 adamantite bars in an hour. That means the profit margin falls between 390,325 and 721,525 hourly.

First make sure you are on either world 358 or 386 (the official Blast Furnace worlds). After purchasing the raw materials, deposit 72,000 coins into the coffer. This will allow you to use the furnace without having to worry about operating it. It will remove 1,200 coins every minute automatically for a total of an hour. Then, start by placing adamantite ore on the conveyor belt first, then emptying your coal bag of coal and depositing that right after. Do two trips of just coal after, and in the second coal trip retrieve your bars from the bar dispenser by clicking on it. Then, do another trip of adamantite ore and coal, and immediately retrieve a second inventory of bars. Repeat this process from the beginning until you either run out of ore, or the coffer is empty.
