I've been interested in some dangers that might exist in combat when someone shuts down magic items, say a quickened dispel magic and a sunder on the fighters favorite sharp stick, and how to try to defend against such nastiness if you're a cautious PC or BBEG.
So how do you defend against this? You could use an orange ioun stone for +1 caster level, and theoretically you could use a moon circlet if you only work on your sharp stick during the new moon... but then making a +4 sword would take a year.
Are there any other ways to make caster level higher or defend against dispelling magic items?
What about if its a magic item that has other spells cast on it? (Say hardening, greater magic weapon, and weapon of awe amongst other things) How does the dispel check work, and how would you defend against it?
