Favour timeline — the windows in Karma's game plan

Read from Karma's seat: which stage windows this plan plays for against Zac.

StageFavouredWhy
Level 1KarmaRQ Soulflare's delayed zone from level 1 is poke almost no tank can answer, and his short-range Stretching Strike can't punish you at that distance.
Level 2Even / skillLayering Inner Flame onto your Gathering Fire Mantra refunds taxes him faster than Cell Division can pick the healing back up this early.
Level 3Even / skillYour 4-5 power overlaps his — the RQ chunk is biggest here but his blob sustain refills most of it, so it nets even.
Levels 4-5Even / skillSame trade pattern: you poke, he soaks and heals off passive blobs, and neither side can force a clean kill yet.
Level 6ZacAt 6 his Let's Bounce and Elastic Slingshot close the range gap and flip ganks, while your front-loaded kit gets no new spike to answer the engage.
First itemEven / skillYour first AP/haste item sharpens RQ, but his HP item plus blob sustain keep pace and hold the lane dead level.
Two+ itemsZacYou have no late scaling and he is an engage tank — his out-of-fog Slingshot or Let's Bounce onto your backline outweighs your utility if you fall behind in roams.

How to beat Zac as Karma: the early game

Zac is an off-meta engage tank — when you land Inner Flame and RQ Soulflare to shove him off the wave, his Cell Division passive drops green blobs he just walks over to eat the chip back, so your poke chunks but does not stick like it does into a dry juggernaut. Still open Levels 1-2 hard: Mantra is up from level 1, RQ on cooldown is real pressure, and your range out-spaces his short Stretching Strike. Bait nothing yet — farm at range, keep mana, and never let his blobs heal a full bar back between your casts.
