are the best fit for Janna. She has so long cooldowns on all her abilities so this makes it better.

A great item in combination with your passive and Zephyr. They can't catch you.

only when your opponents team has a lot of CC. Otherwise I don't recommend this item.

. Nice Ap. Cooldown reduction. And an amazing tool against tanks. take this only when your opponents team have 1 or 2 tanks.

This is a great item for newbies. It solves your mana problem and it gives you some AP. Good item.

Only take this when you are easely getting killed.
