This is a once in a lifetime opportunity. The time is now!
Tr is not the only commodity that will be Rising. The Mort Myre Fungus will be expecting to outperform above all items of the Grand Exchange. Why do I come out with such bold statements? This is why.
Monkey Madness Two will raise the demand of Super Energy Potions which are made using the Mort Myre Fungus. Probably the most volatile resource in Oldschool Runescape. During this quest, you will need to run a shit load, yes stamina potions will be going up, but the demand will soon exceed the supply which will raise the cost of the natural resource. Why did not purchase stamina potions? The general runescape population will not be able to afford such an OVERVALUED item. Therefore the precious resource that is the Mort Myre Fungus, will be the premier commodity of the Grand Exchange and be an out-performer talked for the generations to come.
