Playing against PL in the solo queue all the time is exhausting. It doesn't take much for him to spiral out of control, especially if you're on some mediocre barely functioning team in the first place.20-3 on Chaos Knight and lose to a fed PL.
Hmm unless there's mechanics I'm not aware of, you're never going to get illusions that can survive the gaze(assuming equal/close levels). It does 1500dmg at 16 and illusions takes +350% dmg, so they take 6750dmg premitigation and even with the magic resist on phantom edge, you're still looking at 4050dmg. Considering they don't get flat health, I'm not even sure how many hearts you'd need to have that kind of hp on str alone. Maybe wiki has wrong notation on illusion dmg bonus and it's supposed to be +250%(so 350% total) then it'd "only" do 3150, which is still enough to one shot illusions in most cases unless PL is stacking str items other than a single heart.Medusa gets destroyed by PL late as her ulti doesn't one shot illusions, then she goes oom instantly. DS wall does give juxtapose illusions as well as SD, enchantress, chen, etc.
Her ulti lasts 5secs. After that yeah you're kinda fucked, you might be able to splitshot them down as they spawn but most likely you won't and once the numbers are too big it'll splitshot randomly and not kill shit anymore and you're oom in 3secs at that point and dead. I don't think she's a PL counter, but she does better than most against PL at least. Which isn't very helpful anyway. If your plan is to beat PL lategame, then you're probably seriously fucked.I've played a few long games with PL and Medusa in em. IIRC, it seemed Medusa's ult would clear the illusions, but in 2 or 3 seconds a new illusion army would build up. Since then I haven't liked her as a PL counter.
