I don't see any bane damage listed nor have I seen any improvement
of using the summoned hammer over a FS Hammer.
Not sure when that kind of bonus came into the game originally but its not here.
You will want to use the Hammer of Wrath (or another magic hammer) because it is magical.
After a certain level most undead require a magic weapon to hit (Ghouls, etc.)
Root and Undead Nuke are still your bread and butter as a Cleric
