SMITE

As Kali, kill five gods in one match that are marked for death by your passive.

When a god is marked for death, their portrait and gamertag is to the left of your health bar. You gain physical penetration against that god and gain 80% health for killing them. Whenever the target dies to anyone, a new mark is randomly generated; if you die, the god that killed you is marked.

Kali's default arena build boosts her attack speed to ridiculous amounts, so the primary issue is getting close to enemies. Her leap, Nimble Strike, does the most damage and heals you for a portion of their missing health, and her third, Incense, will stun enemies for a second. That should set you up for kills, with Hastened Fatalis allowing you to stay on them. Sprint, leaps, and dash attacks can and will be problematic. Finally, if you're having trouble staying alive, remember that you cannot die in the four seconds your ultimate is active, so use that to chase down a target if necessary.
