For Drudane, 5k gold or exp for it.
As for chalice, you basically dont need mindread. If you choose hermosa, just help the slayer by killing the prisoner for extra exp. Return to him for reward to complete the quest. Then choose to take the chalice by force and you can slay the whole camp slayers for extra exp, as well as getting the key for the locked chest which contain the chalice.
As for Arben's shield, it will only be there if you mindread Arben in the early day in broken valley. This is like getting Razakel's hammer when killing Barnabus.
