Greetings!
One thing worth mentioning is that the Hidden shrine tends to reduce the durability of the item in the "shield hand slot" (i.e. item on the character left hand - the right most slot on the screen). While I usually just put on all four items when I touch a Hidden shrine to maximise the gain (as Pete explained), if a valued shield is low on maximum durability (by previous Hidden shrine effects), one can substitute the shield with a common one before touching the shrine.
Edit: typo
