Zombie Ward

Passive: Scoring a takedown against an enemy ward (excluding Zombie Wards) within 10 seconds of damaging it will summon an allied Zombie Ward in its place. Gain 3 Attack Damage or 6 Ability Power (Adaptive) for every Zombie Ward spawned, stacking up to 5 times for 15 Attack Damage or 30 Ability Power (Adaptive). At max stacks, you gain an additional 10 Attack Damage or 20 Ability Power (Adaptive).

Zombie Wards grant sight, are untargetable to your team, have 1 health, last for 120 seconds and don't count towards your ward limit.
