Next section is up, voting on a power. Blizz has given the following five options from community suggestions:
Legendary Power 1
You radiate an aura of Hatred. All monsters near you deal and receive additional damage.
Legendary Power 2
Attacks have a chance on hit to cause your current target to be hated by all nearby enemies, taunting them to attack that target for the duration of the effect.
Legendary Power 3
When you are near death, your hatred for your enemies grows, significantly reducing your resource costs and cooldowns.
Legendary Power 4
Elemental attacks have a chance to trigger one of powerful abilities inspired by the Lord of Hatred himself: Charged Bolt, Poison Nova, and Freezing Skull. Lightning damage has a chance to trigger a Charged Bolt. Poison damage has a chance to trigger Poison Nova. Cold damage has a chance to trigger Freezing Skull.
Legendary Power 5
Summons an Evil Force to fight alongside the player for a period of time. This force would take the form of a non-attackable melee pet, and it would be possible to potentially have more than one Evil Force active at once.
So far option 4 is winning.
