Zac's abilities

Passive, spells and ultimate

Cell Division (P)

Each time Zac hits an enemy with an ability, he sheds a chunk of himself that can be reabsorbed to restore Health. Upon taking fatal damage, Zac splits into 4 bloblets that attempt to recombine. If any bloblets remain, he will revive with an amount of Health depending on the Health of the surviving bloblets. Each bloblet has a percentage of Zac's maximum Health, Armor and Magic Resistance. This ability has a 5 minute cooldown.

Playing against Zac

How to counter and exploit weaknesses

1

Walk on his blobs (passive) to destroy them and prevent him from healing.

2

His E is long range but visible and has a windup: side-step when you see him charging.

3

If Zac dies, he splits into blobs that reform: kill all 4 blobs to kill him for good.

4

His engage is strong but he's vulnerable to burst once inside — focus him after his engage.
