Unsealed Spellbook on Ivern is all about keeping your smite on a super short cooldown so that you're able to keep yourself healthy for objective control and early skirmishes.
Perfect Timing on Ivern allows you to take overly-aggressive tower dives and keep yourself healthy from potential assassin counter jungling.
Ivern tends to invest heavily into cheap support itemization and Future's Market lets you hit those item power spikes extra early.
Cosmic Insight is an all-around great utility rune choice for Ivern. The extra Summoner CDR keeps your Smite cooldown even lower and the item CDR lets you get out more Redemption and Locket casts.

Celerity further empowers your jungle clear so that you're able to quickly gallop around the map to pickup camps and join in ganks/fights.
