Charge up, gaining {APPerBurningEnemy} 
Ability Power per Burning enemy. Then, gain {ShieldCalc1} Shield for {ShieldDuration} seconds and rush through a nearby group of enemies, dealing {MagicDamageCalc1} magic damage to each.
After rushing, unleash a {FirestormHexRadius} Hex firestorm that deals a total of {MagicDamageCalc2} magic damage split among all enemies hit over {FirestormDuration} seconds.
Values in braces are scaling variables CommunityDragon does not resolve on this patch; the in-game tooltip has the numbers.

Common builds
TFT Lab does not track item win rates and does not scrape the sites that do. For the current best-in-slot on Kennen, check a stats site, then read the Items guide for how to decide when the BIS is not on the table.
