  • PTR Note: While elements of this quest may appear on the Test Realm, quest progress will not count toward the reward until this patch arrives to the live version of Heroes of the Storm next week.  

New Hero: Probius

Since his activation, Probius has always wanted to prove himself. He may be small, but he made a big difference by warping in a critical pylon during the retaking of Aiur. As the bravest of probes, Probius is eager to fulfill his purpose in the Nexus.

    • Information displayed to all players:
      • Hero Portrait
      • Respawn Timer

    • While only 3 players can be On Fire at any one time, the game is constantly re-evaluating all players in the match.
      • On Fire effects can swap among players regularly based on their current performance.

Design & Gameplay

Body Blocking Improvements

  • Improvements have been made to allied body blocking. 

Time-based Scaling

  • We now have the ability to scale damage based on game time elapsed, which should help the performance of the game, but also more accurately adjust damage values of certain abilities.
    • We have implemented this on Li Ming’s Arcane Orb & Tyrande's Sentinel and will continue to look for other use-cases.

Hero Descriptions

  • Several Heroes have received new descriptions in the Hero Select screen.


Heroes Brawl

  • Bloodlust Brawl
    • The hero selection pool has been curated to favor non-spell caster heroes since they benefit less from the Bloodlust Buff
  • Mage Wars
    • Weekly Brawl quest completion criteria reduced from Play 3 Games to Play 2 Games
  • Silver City
    • Now uses Shuffle Pick for hero selection instead of All Random
Developer Comment:  : With the release of Single Lane Brawls, we've always wanted to try various forms of Hero selection to create interesting gameplay. We know there are avid fans of the completely Random Hero selection (aka ARAM), so that's how we initially released these Brawls. However, over time, we've also received feedback that a truly Random Hero selection can lead to widely imbalanced team comps, which can contribute towards a frustrating play experience. For example, we've seen some matches where one team has 4 Warriors and is unable to effectively fight against a heavy Assassin comp. Combined with the potential of longer games, we think Shuffle Pick may offer your team a better play experience by applying some balance options through Role and Hero Selection. As always, our endeavor is to create the best gameplay experiences for our players so please continue to provide feedback to us whether this change improved your Brawl experience or not.

Developer Comment: When we were first told about the new event “Two Heads are Better Than One”, we immediately set to work on giving Cho’gall’s talent trees a much needed face-lift. A lot of our Warriors were getting Armor updates in this patch and originally Cho’gall was no exception. After playing with a generic form of it internally, we realized we had a once-in-a-Nexus opportunity to do something very different and seized the moment. The foundation of the Cho’gall rework revolves around their new Traits, Ogre Hide and Ogre Rage, which are the keys to success with the Hero. The potential of Cho’gall should be greater than ever, but you will have to make sure both heads are working together in order to maximize your damage output while keeping yourself alive long enough to keep doing it.

Developer Comment: I’m not exactly sure where this Goblin keeps getting the hoards of gold he needs to bribe the Design team, but sure enough he has done it again. The changes to him started off as quality-of-life fixes but eventually evolved into something of a minor rework. Overall, we tried to even out the power level of a couple talent tiers (including his Heroics), while bringing in a swash of baseline changes in order to make him feel a bit more user-friendly. We realize his win rate is above average in certain MMR brackets (and game modes) and that this may be viewed as a substantial buff to him. However, we felt it was important to bring these changes to our players and are prepared to act quickly if any tweaks are needed.
