Aeterna Noctis has a variety of weapons for the Shadow King to wield. The Axe, the Scythe, and Love are both great melee options, but what if you want something with a longer range? Arrows of light, one of three you can shoot in the game, will do the trick. This is the place to find them.
Your first target marker will eventually lead you to the top of the Tower of Light. It’s a long climb, as you make your way through damaging beams of radiation and escape from a giant sword that sends you bursting with spells. When you finally reach the top of the tower, you’ll face that giant sword in a boss encounter.
To take it down, you need to know its three ways of attacking. First, it will crash into the middle of the arena and spin around, summoning columns of light. Run against the wind and look down at the ground to see where you can safely stand when the beams of light emerge. For the second attack, the sword will try to stab you right down. Again, keep an eye on the ground to see where it’s targeting, then tap your dash to avoid it. Finally, the sword will summon four portals when a giant blade lands on the screen from the left or right. To avoid this, run in the direction of the falling sword and rush into the portal. When you float to the top, dash again to clear the blade, as it will remain on screen for a moment. You will need to do this a few times, on alternating sides.
After each attack, whether you dodge the damage or not, the giant sword will move closer to the main platform and summon several platforms. Quickly climb these, dodging magic spells, to hit the sword’s red jewels with aerial attacks. Five hits will knock it down.
Once it’s over, you’ll be treated to one of the game’s adorable cutscenes. Then you will get the Arrow of Light in the next room. They can be used to not only hit enemies from a distance, but also to hit glowing targets. These targets can open locked doors, create platforms, and more. There are a bunch of new areas to explore once you’ve unlocked the Arrow of Light.
