Sejuani, Nasus, Sion are all frontline units with high HP value who make great use of this mod.

A very strong all-rounder tank item with the added value of healing and ‘refreshing’ the holder every 5 seconds.

Every Rogue comp and reroll comp that utilizes Ekko/Warwick has an easy time fitting 2 Zaun with a +1 emblem which is why Katarina, Zed and Gwen are easy options.

Urgot is the best user of this Chem-Mod.

The closest thing you can compare this Chem-Mod to is a Hand of Justice that gives buffs depending on how much HP you have instead of randomly between rounds.

Non-Zaun units shown are here either because they are often played or easily played together in Zaun comps OR use the Chem-Mod so well they are mention purely for their synergy and strongest board potential.

Units like Warwick are never the final holder of these mods and are often here just to show that they can be good ‘Chem-Mod’ holders. The first few units displayed are always Zaun units as they are by the most common users of Chem-Mods.
