Mutation Creation Contest Winner
''We are proud to present the winning entry of our first Mutation Creation contest, as designed and submitted by Saito. In this weekly challenge, vile replications of the Koprulu sector's greatest heroes inspire Amon's forces as they lay siege to Augustgrad. Do not back down in the face of their presence, and focus on saving the city.''

This mutation applies to "Rifts to Korhal". Along with each attack waves, powerful enemy heroes will spawn. These heroes include Jim Raynor, Tychus Findlay, Nova Terra, Artanis, Karax, Zeratul, Kerrigan, Zagara and Dehaka. This mutation was the winning entry of the Mutation Creation Contest.


 * Heroes from the Storm: Every attack wave will be led by a random Hero of increasing power. Each Objective point is also guarded by three random Heroes.


 * Inspiration: Enemy Heroic units increase the attack speed and armor of all enemies within a small range.


 * Hardened Will: Enemy Heroic units reduce all incoming damage to a maximum of 10 when any non-heroic enemy unit is near them.
