League of legend all items that buff shield for Rumble

I play Rumble and want to use item that buffs me when my shield turned on.

May you know which suites for me?

Ardent Censer, Mikael's Crucible, Shurelya's Reverie, and Redemption all increase shield strength. However, they all share the same unique passive, which means they don't stack if you have more than one of them. Revitalize is a rune in the resolve tree that also buffs shielding.

I will add, however, that none of these items are good on Rumble and the playing for shield strength vs. raw damage will net you little benefit. I recommend checking out sites like u.gg and leagueofgraphs to find what item builds and runes are working best for your champion on the current patch.
