I got it to work first try when i went to do it. Very easy to activate and beat with it!
Oh and i had all wolverine items equipped when the boss started and then changed it all to Quicksilver and when i died and made it slow it respawned with Wolverine items equipped while in slow mo so the health came back faster than anything that hurts.
