Simple really...
Build your cleric or favored soul, then never bind to any taverns.
Go into any dungeon and die on purpose.
You will find yourself inside the opening quest.
Play the quest thru and pick up your eternal wand of spark of life at the end of the quest.
Then head over to the catacombs (p2p) to pick your eternal wand of cure minor wounds.
You can thank a cleric friend of mine who rerolled and rushed back to the party without binding for this discovery.
Cheers
