* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.

* Unless Puck is facing the direction he wants to blink while in Phase Shift, the Venomous Gale and Poison Nova combo consistently ticks many times over several seconds, making it very difficult to use Blink Dagger towards the other direction. Puck's slow turning rate makes this even worse.

* Ice Path serves as a large obstacle to stop Axe from chasing down fleeing stragglers to kill with Culling Blade.

* Both Poison Nova and Venomous Gale hit invisible units, so Meld cannot be used defensively.
Additional:
* Venomancer's entire arsenal deals lingering damage over a long time and therefore burns through her Refraction very quickly.
