It has no cast time, but has a channel of around 0.25 ish seconds. Just like how Varus can't shoot arrows while shooting his arrow while raining arrows while throwing corruption.

So I feel if your character attacks fast enough that he would've landed an auto-attack in that time span, then he shouldn't take the time to use hydra since its damage is at max an auto-attack in damage.
