So I want to get extremes since apparently there is a big difference between them and supers. How much would this cost and what would be the best pots to make?

 

I also need to train smithing, crafting, and construction and thieving for some quest. For con Im assuming its still oak larders and thieving I will probably do PP since I kind of find it enjoyable. But I am not sure what the best way to train crafting and smithing without losing to much money.

Personally, I don't think that extremes are that much better than supers :P

 

If you go onto the Runescape Wikia (not the runescape's offical wiki), and you search for calculators, there should be a calculator there named "potions" (under herblore). It has all the up to date prices of the herbs and potions, ect ect. It helped me out a tonne.

Extremes are significantly better that supers.

 

You should aim for at least 89 herblore and make extreme strengths and attacks. A couple hundred will last a little while, then you can make some as you need to.

 

You don't really need the other extremes for general slayer, unless you plan on ppsing steels or miths, then extreme magics are a necessity.

 

Once you have the money, upgrade to overloads. These are mostly for bossing and maging, so leave a few extremes for general purpose.

Herblore:

Generally I tell most of my friends who have the same goal (89 Herblore) to go with super strength. (its relatively cheap and efficient)

I also link them to this page: http://www.tip.it/runescape/?herb

It is a Herblore cost calculator that calculates GP/XP for both (UNF)+Secondary and Herb+vial+secondary.

Crafting:

For crafting I would make orbs using molten glass and a glass blowing pipe.

A calculator can be found here: http://www.tip.it/runescape/?page=crafting_calc.htm

Smithing:

The cheapest way to do smithing would be to make gold bars with Goldsmith gauntlets after the Family Crest quest.

Hope this helped!
