If Androxus uses his Reversal (he will), use your just before he attacks you with it, then Whirl to go right behind him. If he isn’t pro, he’ll get confused: you can take advantage of that to finish him off.
don't try to repeatedly stun the enemy because the enemy can be stunned only every 3 second(unless you're using the wekono's wrath legendary) and that goes for every enemy. otherwise it's a good plan to use your stuns in 1v1
