Do not use Improved Wild Empathy on the attack dogs in the first part of Lords of Dust.
Not unless you want to wait ten mintes to be able to continue to the rest of the quest.
I like both options really.
On one hand, I hate having to uncharm any monster to proceeed with a quest, but at least that is an easy fix. And some classes can occcasionaly get a clickie or scroll or something that charms something.
I suppose killing everything could occasionally have a valid story reason.
But in this case..... a dog?!
Why is a dog important?
I want to take it with me!
