Mana Addict (lv1), Nether Wind (lv4) – Mana Tap, Burned Flesh (lv7), Phoenix (lv10), Pyromaniac (lv13), Ignite (lv16) – Fury of the Sunwell, Flamethrower (lv20).

The Flamestrike standard build focuses on enhancing Flamestrike’s damage and potency, providing him with an even more powerful set of equipment and greater combat capabilities.

Maps of Kael’thas

His high AoE and damage to teammates make him an extremely effective pick on smaller maps where fights and skirmishes are frequent. His powerful tsunami also makes him a valuable pick on maps were quickly killing a large number of low-health targets is crucial, such as the Tomb of the Woman. Spider Emperor, Braxis Holdout, and Infernal Shrines.

  • Verdant Spheres should be used with Flamestrike when he needs waveclear.
  • Gravity Lapse should only be buffed with Verdant Spheres to catch an enemy Hero hiding behind minions or to stun multiple enemy Heroes.
  • Phoenix can be used to zap enemy Heroes, destroy Mercenaries, clear waves of Minions, and to encircle or protect Forts and Keeps. Its relatively low cooldown encourages him to use it freely.
  • Pyroblast channel behind the wall or front line of him. Try to use it proactively and early in fights, instead of saving it to finish off enemies.
  • Gravity Lapse is difficult to hit. Take the necessary time to land it, as he will not be able to defend if it misses the desired target (s).
