In this Hades guide, we’ll tell you what it means when a weapon in the Arsenal Room (the room behind Zagreus’ bedroom) is glowing purple.
Purple weapons earn extra Darkness
Once you’ve unlocked a few of the weapons in the Arsenal Room, one might look different the next time you return. A weapon that is glowing purple and has a purple cloud around it will give you a bonus if you use it on your next run.
When you approach, you’ll see a note at the bottom of the screen with “+20%” and the icon for Darkness. When you equip that weapon, you’ll earn, as you’d expect, 20% more Darkness every time you pick some up. (If you don’t equip that weapon, you’ll still earn Darkness normally.)
Choosing this weapon is a great way to earn Darkness faster so you can level up your Talents (skills or abilities) at the Mirror of Darkness.
