His skills are enhanced during the fusion period. Use Again: Zhask immediately gets off the Nightmaric Spawn and loses enhancement.
Counter / cooperate relationship
Zhask is strong against burst damage heroes like Aldous and Paquito because his high HP after fusing with his Nightmaric Spawn, makes him tough to burst down.
Zhask is countered by agile or long range heroes, such as Pharsa and Cecilion, because they can quickly step out of range of his immobile Nightmaric Spawn.
