Strand of Prayer Beads

The Strand of Prayer Beads is one of the best magic items out there. Why? Because it provides a +4 caster level bonus for 10 minutes. Very few items provide this kind of bonus. Another aspect of this item is that is does not take a magic item slot so you can have and use multiple strands. Combine this item with one of the best offensive divine spells, Holy Word and what do you get?

Any opponent with fewer hit dice than your level is instantly defeated with no saving throw (aka paralyzed at least a minute). Any opponent that isn't at least 4 levels higher then you is blinded and this typically means they are severely limited. Sure, they get spell resistence, but you have that extra +4 to overcome it.

It seems the primary reason people don't use Holy Word is that it will hit their own party members that aren't good aligned. Simple solution: screw em. Eventually they will convert.
