Is there a way or a spell to remove the hexed condition on my party members? They got hexed after drinking from a fountain in Trynton.

if you don't have any spells yet the Fountain in Arnika (temple with Lord Braffit) will fix everything but death

The fountain in Arnika temple can only be used a few times before it stops working. I recommend only using it if somebody is diseased or drained (and disease should really be cured immediately if at all possible).

In the case of being hexed by the Trynton fountain, the condition will not long enough for you to use the Arnika fountain to cure it, unless you teleport there with a Return to Portal spell; even then, it isn't worth using the fountain's limited charges to cure a condition that will go away on its own.

I agree with you but the question isn't should I use A or B tactics... he can make his own mind up
