Not sure how to add a screenshot but my Blessed Hammer tooltip says -2,147,483,648 damage with a modifier, dealing 0 damage. This is at 39 ranks currently
Mine is also -2B when all the buffs are active, but it still mows down enemies. Try the test dummy in K-town to see if you are actually doing 0 damage
is this just a tool tip error ?
Max signed 32 bit integer is 2,147,483,648 and if that value stored exceeds that value it shows -2,147,483,648. So it seems like Blizzard has a data problem with how they are storing those huge numbers in their database?
