Riggilo

Riggilo is an adventurer who is found looting Durlag's Tower. See the Durlag's Tower Walkthrough for details.
He can be found on the third floor of the tower. If you kill the succubus, Kirinhale, you can give him a lock of her hair and he will give you a potion of cloud giant strength in return.
You may find it more lucrative to sell the lock of hair to a wizard merchant, e.g. the one at High Hedge, for . If you agree to help Kirinhale instead of killing her you can still give him the Lock of Hair from Kirinhale in return for the Potion of Cloud Giant Strength. Return to Kirinhale to get 4000XP for tricking Riggilo into taking her place. Finally return to Riggilo and he will attack you, and you can take the Lock of Hair from Kirinhale from his corpse.
There is no Reputation hit for killing him in cold blood.
