thats what her wiki says (http://millenniumwaraigis.wikia.com/wiki/Sherry) , but i cant personally comfirm it for the simple fact that i lack sherry.
BTW , seeing your team , all you're getting buffed are bernice , the soldiers and iris. All in all decent units to get buffs on , since defense and hp are good stuff to have on blockers , but not sure....
I'd still take spica's buff over them to be honest and try to AW sherry after.
