Arrow Nemesis will look familiar, as he is one of the legions who escaped earlier in The Astral Chain Narrative. He is an intelligent opponent who will take to the air to launch devastating attacks and use the fragmented nature of the arena to his advantage.
Astral Chain: How to beat Arrow Nemesis
Arrow Nemesis likes to operate from afar, so it's best to fight him. The Chimera can launch devastating arrow attacks against you, so it's hard to keep it off, allowing your own Legion to interrupt their type of attack.
The arena you fight Arrow Nemesis in will consist of multiple small platforms, and Arrow Nemesis will settle down to create energy barriers as it attempts to trap and hit you with projectile attacks. You have to use your Legion Slash attack to break through these walls by lining up the slash to get through the three light lines of energy.
Don't let the boss stop you for too long, as projectile attacks on small platforms are extremely difficult to dodge. Just keep going after the boss, using your wand weapon to quickly set up combos, and use Slash Attack when possible, as it would do a lot of damage to Arrow Nemesis.
Use your chain to chase Arrow Nemesis between the platforms, but be careful as he can knock you over if you are near the edge. It won't kill you, but it will take you health. Because this fight does not include any announcements, there is no finisher healer available, and you rely on the healing items you managed to collect in the level.
If you keep the pressure on, cut the energy walls quickly, and constantly stay on the face of the Legion of the Arrow, you'll reap the advantage they have at distance and this fight will be a snap.
