-Pincer Sweep. Inputs when Dante is near. Jump or run to dodge. Minimal damage.
-Geyser Eruption. Erupts 4-6 geysers. Readies by lowering, and red/yellow swirls appear by Dante's feet. Simply run to avoid. Fair damage.
-Jumping Crush. Jumps and lands on Dante. Jump at the right time to avoid. Fair damage.
-Fireball. Fires a fireball at Dante. Charges a white orb in its mouth and sends it flying at high speeds towards Dante. Hide behind obstructions or roll to dodge. Moderate damage.
-Poison stinger. Swipes at Dante when he is on his back. Jump to avoid. Minimal damage.
Use firearms to chip away at his damage when far away. When in close-range, though, try to get a few swipes in with Alastor. Once you identify all his attacks, you'll be okay. His fireball is the one to watch out for - he uses it often and it takes a fair chunk of Dante's health. Your main aim is to jump on his back, and swipe away with Alastor. Don't stay all day, as he will eventually try to slash at you.
