Outside of this spell however, Helm should completely prevent the counter. Do note that the barrier is dispelled after taking too much spell damage, so if Michael has already stacked a lot of spell damage you might find the duration shorter than you'd expect (should still be more than enough to get off some spells though).
Ok so do I need to make sure that Michael has not attacked me before casting spells on him?
Here is the situation that has happened to me every time except once now, I cast the Helm on myself, then I go to cast truth on Michael and I still die instantly. Then I try using helm on myself and casting the centaurs ultimate on Michael and same thing I die instantly so I don't know what I am doing wrong. any help would be appreciated!
