Found out the secret

The previous post in my blog stated I discovered that Mandragoras in the past used a regen move on characters, after a bit of testing with other people I discovered how to triger it as well, it never did the move on characters 1-75 for some reason but me, and then another character with a certain quest title had pondered up and got the regen effect as well.

So completing a new windurst quest labled Babban Ny Mheillea after completing the quest the mandragoras in the past will love you and shower you with regen...even if you slaughter them shortly after.
