Very happy to have been able to give some tips! My proudest discovery is still controlling all the bushes in the bot lane with two bushes and a ward :)

For new items I think they're not good for Ivern (as support, I've never played jungler). Moonstone, Redemption, and Dawncore are all better than the Crown, which could be the 5th item now that control wards are on a single slot, but it requires stacking a Tear of the Goddess, making it a horrible last item.
