DmC: Devil May Cry - Mundus Spawn Boss - Hell and Hell Difficulty (No Damage)
I am using Super Dante in this video, awarded to you for completing the Dante Must Die difficulty. Mundus spawn is very easy on hell and hell, as his attacks are very predictable and he only has a few different ones. His main attacks are when he swings his arms at you, this is easily noticed and you can dodge to avoid them. Before you pull Lilith out for the first time he will only send a music wave out once he teleports away, after the second time though it is twice, then two in rapid succession.
For the first phase, activate devil trigger and use the Arbiter on his legs. Start on the back right one (Your right) and as soon as you see his chunkier left lifting up move to his next leg. Hit the next leg 2-3 times then roll to the front of him. If you don't do this quick enough he will spin around and hit you very quickly, which is difficult to dodge. Repeat until you are able to pull Lilith out. Activate Devil Trigeer again and use the trinity smash combo on either Lilith or Mundus' spawns belly. This should get Liliths health down to about 1/4.
For the 2nd phase, attempting the tactic you used in the first phase is risky because he is much quicker at swinging his arms. What you want to do is use demon pull on the arm sticking out of the right of his body (your right). Then use Angel lift to get up to the eye on the said hand. Keep attacking this with the Aquila while devil trigger is active. As soon as you see him about to swing for you, use Angel evade to get away then pull back with the Angel Lift. The eye on his forehead will eventually open, you then need to attack this. He will pretty much die after a few hits of this eye. All you need to do then is pull Lilith out with Demon Pull and attack her with the arbiter.
