Wraithfire Blast applies a ministun on impact followed by the full stun, so it cancels channeling spells even through status resistance.

At max level the total disable time from Wraithfire Blast is 4 seconds from a single spell.

Skeletons last 45 seconds and benefit from aura items like Assault Cuirass and Vladmir's Offering.

Skeletons can tank Roshan, tower shots and jungle camps, so build them up before a fight.

Managing when to toggle skeleton generation on and off to build an army before a fight separates great WK players.
