are there multiple items that have magic absorb? or is it just spirit shield?

additionally, how do you mitigate magic damage, if all you have is some random magic reduced integers?
do defense and block go into the equation?

Mostly I am asking for pvp reasons. I am a maul druid on hardcore ladder

Thank you for any useful info you can give.
