As of right now, strength potion making costs about 3.5 gp per experience point, which is about half the price to do engery potions.
Xp from 81 to 99 is 10,841,613 XP
You would lose 37,945,646 gp, which is not bad at all, and fairly cheap.
http://runescape.wikia.com/wiki/Herblore_traininghttp://runescape.wikia.com/wiki/Scroll_of_cleansingGet a scroll of cleansing, saves money on making potions. Obtained from using tokens from dungeoneering to buy the scroll.
It costs 20k tokens. and its abilities are very helpful for herblore.
- A 1 in 8 (12.5%) chance that the player will make a potion twice as fast as usual.
- A 1 in 10 (10%) chance that when adding an ingredient to a vial of water, coconut milk, or unfinished potion, it will not be used up, leaving the player with an extra ingredient. This effect includes juju potions and extreme potions and can potentially save both the herbs and secondaries while making juju potions. This can be extremely advantageous considering Juju herbs must be grown by the player at a limited rate.
EDIT: This reminds me, I should create a guide for herblore. Waiting till after EOC for price stabilization ,if that happens.
