Eruption is ****ing amazing! Today I was going up against some Kirby player who just loved to spam his down special attack. For the most part, I was punishing him for it, but at one point I ended up charging eruption, not entirely sure how. Well he tried to punish me for it by dropping on top of me. I released Eruption, and WHILE HE WAS IN THE STONE FORM he was instantly KOed. At first I thought he had transformed out of the rock, and that's what caused him to suffer a KO, but later I was up against another player using the same tactic, and it worked again! Now I don't know if this is new information or not, but this is the first I've heard of it.
I also had this awesome moment where I was falling from the sky, gonna try and Quick Draw away, guess my input messed up and I was stuck charging up Eruption. I was playing against a Pit player and he was charging a Usmash (which has incredible range). Not entirely sure how, but I released Eruption as he released his Usmash and Ike's attack took priority.
I'll upload a few videos of the above instances and post them on here later. Vidya:
