Thanks to the aid of Nyx, Zagreus can increase his chances of escaping the Underworld by unlocking upgrades at the Mirror of Night. You won’t have access to them all immediately, but as you earn Darkness and other house upgrades, you’ll grant Zagreus some seriously powerful new abilities. Below, we’ll break down all the Mirror of Night upgrades and prices, as well as giving our advice on which ones you should be grabbing first.

How the Mirror of Night works
The Mirror of Night is found in Zagreus’ bedroom in the House of Hades. By interacting with it, you can spend Darkness collected during runs to upgrade Zagreus with increased powers. Only some powers will be unlocked at the start, and you’ll need to spend Chthonic Keys to unlock later powers.
Additionally, each Mirror of Night power comes with an alternate version you can invest in separately. Default powers are shown in red, while alternate powers are yellow. You’ll need to pick between activating a power or its alternative version, as only one can be used at a time. Eventually you’ll unlock the ability to refund your spent Darkness for the cost of a Chthonic Key, but choose carefully before then!

Which Mirror of Night upgrades to get first
While it’ll take a while to unlock all of the Mirror of Night’s powers, there are several well worth investing in as soon as you can. In our opinion, You’ll want to collect at least the first level of Death Defiance as soon as possible. The first level is cheap, but the later ones will require some saving. Next, unlock Dark Regeneration as quickly as you can to allow healing every time you collect Darkness. There aren’t many ways to heal in Hades, so take advantage of them.
With healing and death sorted, one of the main things that’ll help you progress is increasing your health bar, and that means investing in Thick Skin. Thankfully it’s a cheap power to invest in, which will reward your early runs greatly. Once you get used to the game, Golden Touch will massively increase your money income, meaning you can save up for the more valuable items available in later regions.
And that completes our Mirror of Night guide for Hades. Hopefully by reading this guide you’ll better understand what all of the powers offer, and have an idea of what you want to want to invest in early. For more Hades guides, click here to head to our hub page for the game.
