Explosive Mutation

Infested Kerrigan has mechanics to keep herself alive.

When Kerrigan has her Organic Shield points exhausted, it'll remain static and invulnerable to all damage, the player will see her portrait and some quote, then, she'll start a super-high mutation process that will lead into a huge explosion. The process takes 6 seconds to be ready, then, a huge explosion will critically damage (over time) any enemy unit standing on all the area around her. Damage based on distance to Kerrigan. The explosion lasts 1.5 seconds.

After that, she'll remain stunned (static) for 15-20 seconds or until 25% percent of life is wiped off, unable to cast any ability. During that time, the player can deal direct damage to Infested Kerrigan. After that stun time, she will restore all her Organic Shield points and keep her path.
