With the release of update 1.6, Stardew Valley unveiled nine new achievements, among which is a secret one dedicated to the game's "most powerful weapon." Infinite Power stands as the latest challenge, tasking players with unlocking an end-game sword — an indestructible blade capable of cutting through anything and vanquishing any demon. In this guide, you'll discover how to unlock the new Infinite Power achievement by forging this legendary sword.

It's worth noting that players who have already achieved Perfection in their playthrough should first check their achievements, as they might already possess Infinite Power. With that being said, here’s everything you need to know about Infinite Power.

Stardew Valley: Every Achievement/Trophy (& How to Get Them)

On your way to 100%-ing Stardew Valley, you will need to unlock all achievements and trophies; here’s a comprehensive guide to help with that.

How to Achieve the Infinite Power Achievement

The Infinite Power achievement requires you to unlock the Infinity Blade. This end-game weapon is forged by combining the Galaxy Sword with Galaxy Soul three times. As the achievement’s description suggests, the Infinity Blade is the strongest weapon in Stardew Valley, hence the title “Infinite Power.”

Players who have already unlocked the Infinity Blade will find the achievement unlocked from the outset. For those who haven’t, equipping it from the inventory may trigger the achievement.

How to Get the Infinity Blade

Here’s how to get the Infinity Blade—and unlock the achievement:

Get the Galaxy Sword. With a Prismatic Shard in hand, stand in the middle of the Three Pillars in Calico Desert. This action will summon the sword.
Get three Galaxy Souls. Purchase them from Mr. Qi (40 Qi Gem each) or trade them for ten Radioactive Bars at the Island Trader spot. You might also find these Souls in the dangerous Mines and during the Cavern Invasion challenges.
Collect 60 Cinder Shard. Obtain these shards from their respective nodes or find them in Fish Ponds and Fishing Treasure Chests.
Forge the Sword and Soul. Place the Galaxy Sword and Soul in the Forge and combine them. Do this three times to get the Infinity Blade and unlock the Infinite Power achievement.

Following the transformation of the Galaxy Sword into the Infinity Blade, the weapon retains its ability to accept upgrades. Players can enhance the sword's stats and incorporate speed or defense buffs to further augment its effectiveness.
