There's 0 chance of anything happening if you CC the enemy #1, which you have 100% chance to accomplish. And no, you won't get oneshot if you're being lazy and do not, we must be playing different games. But just in case, you can. And Shroud + Web is aoe hard CC which ignores armor for 3 AP, it is the ultimate aoe hard CC, because the enemies can move and can't target anything outside melee so at best they can heal themselves. 99.9% of the time you won't need it (if you're at the point you can CC 3-4 enemies with 13 AP surely you can CC 1 with 6) and can just use some normal CC but since the argument is in purely theoretical area at this point where hypothetical enemies are 1shotting your party it is going to work even if the enemy has 100k magic armor and is immune to all damage. But I'm just wasting my time arguing with you since you're clearly not capable of civil discussion and probably think you're way smarter than you actually are.
