I have extra exp for farming, dungeoneering, construction and firemaking. Which are skills I'd never train since I hate them that much.

 

Anyway, is there a way to move the extra exp I have there over to skills I actually do use like herblore, smithing or crafting?

 

If not these are just useless.

 

And to add to that I didn't choose any of these extra exps, they came because I got several stars that only give me choice of one skill.

No it's not, unless they bring back Vic the trader, who allowed you to trade bxp from one skill to another, but you received much less xp on the trade.

No, you can not currently transfer bonus XP to a different skill.

 

 

 

In September there was an NPC named Vic The Trader who took your BXP in exchange for credits which you could use to buy prismatic fallen stars, but he's gone now. http://runescape.wikia.com/wiki/Vic_the_trader

I would exclude items from these skills.

 

However if I did that my ice hearts would drain so fast that I wouldn't be able to use them when I really do need them. (such as when I'm training a skill and wanna finish everything I have and don't want more of that.)

 

So the best solution is to cash out which I will be doing from now on. It's a shame I can't do anything about the a lot of extra exps in skills I would never use, but I just have to live with that there is nothing else I can do.
