Cat Scratch
As Bastet deliver the killing blow to an enemy Gods in a single match with the damage from your Cats.

— Bastet's ultimate – Cat Call – summons three cats that will slow and damage nearby enemies.
They will prioritize targets affected by your passive – Open Wound – that allows you to make target bleed for three seconds after hitting them with any of the three basic abilities.

→ For the achievement, pick a weak or low-life target and apply your spells on them. Then use your ultimate when the target's life is low enough, and the cats will finish the job.

Thanks to MetalGearFR33N0 : You only need to get one kill for the achievement, even though the description might appear confusing.
