The thunderstone??

[Turd Cutter]

So i just finished the quest. I got the stone from the wife. But it shows it as a DE-buff?? I read online it gives some stat increases. Anyone have an idea? I did not steal the stone. I stole it and reloaded the save because it gave me a debuff. Completing the quest and not stealing it still gives you the same debuff? Some people online have reported that it will be listed in the buff area?? May be I have too many buffs? I do have many?

The thunderstone gives a buff. You can complete the quest and give it away and then pickpocket it back with no problems. Or pickpocket it, give it to the other person that wants it to get both rewards and then pickpocket it again. You'll still get the buff.

I don't think you're meant to steal the stone DURING the quest though, but I haven't done any testing on that.

it shows as a debuff until you go to one of the 2 that want the stone and say youre going to keep it or give it to them and pickpocket it back.
