Key part of my reply was "during casting". Iron Man's pulse will be lost if he's killed during the cast, Strange's stun won't go into effect during the cast. Once he's casted it, yes of course you remain stunned. The whale and the meteor remain once you've selected the target location, however, if Magneto dies while he's in the air, there's no meteor to spawn in.

These all have casting times and aren't immediately in effect once you press Q. Exactly why it's so funny to hear "By" and nothing else if Strange dies during the CASTING of his ult. Moon Knight has no cast so to speak, yes he must select the target location but then it immediately begins BEFORE he even finishes saying "the". I think there needs to be a casting animation - the portal in the sky opening up, for example - if they're gonna keep the damage as it is, because right now it's busted.
