You can avoid getting parried with Ivy's Stone Form

As Ivy, if you light melee and immediately Stone Form afterwards, you can hear the sound of being invincible and you do not get parried if they try to parry your light melee

Pretty sure this is a ping related bug, it's happened once and i was unable to recreate it or it's just frame perfect
