New to the game, found the "Ice cream" relic.

[Euphytose]

This seems very, very powerful, borderline broken. Are there other relics like this?

[Hurodrik]

Yup. There are relics in this game that are so powerful they might completely change your run if you find them soon enough, like the unceasing top.

[MechaTails]

Considering the enemies start doing like 40+ damage per turn, we need all the powerful relics we can get haha

[Nixmachine]

I'd say Paper Krane is strong too, although it's Silent exclusive relic.

Plated Armor is the most insane one :D Can´t believe it didn´t got nerfed so far.

[Sentient_Toaster]

Dead Branch and Snecko Eye are both run-defining.

Here's a run where I got Ceaseless Top as the first Relic, I've never used it before but my half-baked strategy worked for the most part:

The Top makes you draw if you don't have cards in your hand, so naturally I went for low (0-1) cost cards and things that give me energy to get rid of 1 cost cards. I had a single card that channeled Darkness, and a single one that channeled Frost, but it quickly stacks up. All the 0 cost defense cards give you protection too as you cycle through the deck. Lots of Claw cards, they get stronger the more you use them. Hologram was nice because it lets you grab a 0 cost card and exhausts itself, so you dont worry about paying for it again.

Etc., I'm sure this is a known strategy.

I would have liked to be able to channel that Darkness more often. I had a Static Discharge (evoke when you're hit, to keep the Darkness coming) and Loop in the deck, and that helped make it devastating.
