Probius coming to the Nexus
Probius warps into Heroes of the Storm! Blizzard Entertainment revealed the next specialist hero during the HGC 2017 Katowice Western Clash livestream. It is not phase-smith Karax as I predicted, nor any known StarCraft hero. Instead, it is a wildcard (like ETC, Brightwing, or Murky who didn’t exist in-game or in written media before).
Probius is a StarCraft protoss probe which builds pylons and warps cannons onto the battlefield. The hero should be in the PTR on Tuesday.
The official trailer played at the end of the Fnatic vs Gale Force match 2.
