Stolen potion

In the sidequest "Stolen potion" you help Dilos get back his potion that someone stole.

Dilos suspects it is his neighbor Bala. You go over to her house and see that there appears to be a potion there in a locked room. Bala claims she hasn't stolen anything.

If you go outside and enter Bala's house through the side you can enter the locked room from a different entrance. Pick up the potion and return to Dilos.

Talk to Dilos again to receive 10 Pix for the help.
