* Skywrath mage also has a terrible time fighting against anything that isn't a hero.

* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light

* Any hero that can nullify effects of Chronosphere: (Omniknight, Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (Outworld Devourer, Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.

* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.

* Primal Roar pierces Rage and can disable Lifestealer in fights.
