About reseting skills

can i rest skills only by iron bits?
i know there is a special potion u can rest all skills, but u can get it only once? or u can buy it or craft it or get from mob?

The potions you get only reset either attribute points or devotion points. Skill points must always be bought back at the Spirit Guide. The others you get from quest rewards and they can also drop sometimes from Nemesis.

And you need to pay attention to that,

  • Attribute points reset potion is only in AoM(and FG).
  • The Mastery Level Redo at the Spirit Guide is also only in AoM(and FG).

In other words, if you play the base game only,
you can never redo the Attributes and Mastery levels.

but only by iron bits? if so why it’s expensive?

It gets more expensive the more often you use it. The idea is not to make major changes to your build, but tweaks here and there if needed. Iirc there is a max figure for resetting skill points, but never having used it that much I don’t know what it is.

can u tip me a map for farming iron bits?

Not really. Just pick up yellows and above and sell them, should get you a fair amount in a short time.
