See Alexstrasza's page for all abilities and talents!

  • Abundance would originally have indiscriminately healed, but devs found it didn't feel right
  • Alexstrasza chooses the landing point for each fireball and her own landing in Cleansing Flame
Humanoid skins
Dragon skins


See Hanzo's page for all abilities and talents!
  • features needed to be made a bit thicker/bulkier than the Overwatch model
  • basic attacks tend to be slower, but deal a little more damage than other ranged assassins
  • Scatter Arrows have a telegraphed area for Hanzo that shows initial ricochet
  • Hanzo was in development as early as April 2017
