Terran
Widow Mine
= This unit has a new missile ability called Unstable Payload.
Unstable Payload is an auto-cast ability that initiates once the Widow Mine is burrowed. It cannot be turned off unless the unit is unburrowed. This ability launches a missile at a target within 5 range, then starts to rearm another missile. Unstable Payload does 160 damage to a single target and 40 splash damage. The missile auto-acquires cloaked units. The missile auto-acquires temporary units like Hallucinations, Infested Terrans, and Locusts. It takes 40 seconds to rearm the missile. The cost is free for now.
= The build time of this unit has increased to 40 seconds.
Protoss
Oracle
= The Phase Shield ability has been removed
= This unit has a new ability called Void Siphon.
The Oracle channels a beam at an enemy structure that deals 3 damage and harvests 3 minerals every second until canceled. (Note: This ability will not cause the opposing player to lose minerals.) The range is 7. The damage/harvest effect ticks when you cast the ability and every sequential second following. Void Siphon costs 50 energy to cast.
Mothership Core
= This unit’s Purify ability has changed.
When a player casts Purify on their Nexus, it grants the Nexus the ability to attack, no longer requiring the Core to attach itself. The Nexus weapon has a range of 13 and a damage of 20. Purify now lasts for 60 seconds and still costs 100 energy.
= The scale of this unit has been lowered to 0.8.
= This unit has had its shield/health lowered to 60/130.
= This unit now costs 2 supply.
