An APC mirror your passive cheats — trade rotations evenly and cast the extra seven seconds they don't get.
Track: Ziggs's W — Satchel Charge (20–12s cooldown). His knockback escape — and your tower’s execution clause; he is catchable while it is down.
Read from Karthus's seat: which stage windows this plan plays for against Ziggs.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Ziggs | Ziggs' Q out-ranges Lay Waste, so he pokes and zones you at level 1. |
| Level 2 | Ziggs | At level 2 his W and E mines control the wave and deny your trades. |
| Level 3 | Ziggs | Level 3 he keeps out-ranging and out-shoving you off farm. |
| Levels 4-5 | Ziggs | Levels 4-5 his lane lead holds as he chunks you from range. |
| Level 6 | Karthus | At 6 your Requiem matches his ranged threat and flips kill pressure to you. |
| First item | Karthus | First-item Q burst and pick threat punish his total immobility. |
| Two+ items | Karthus | With 2+ items your range, picks, and Death Defiance win the teamfight. |
Levels 1-4 belong to Ziggs: his Q out-ranges your Lay Waste and his W/E zone control shoves you in and denies farm, so accept a passive early game and last-hit carefully under tower. Dodge his Bouncing Bomb angles, never stand in his minefield, and remember Satchel Charge deals percent max-health damage that armor alone won't blunt. He out-ranges you with a spell that is cheaper than yours, so give up the poke war entirely and last-hit under your own tower. Watch the mana. Keep the wall for his satchel: a slowed Ziggs with no escape is the only way this lane produces anything for you.
