Pokemon Legends Arceus: How to get Ursaluna by using a Peat Block to evolve from Teddiursa

If Ursaring never quite satisfied your desire for a bear Pokemon that could maul your enemies, Pokemon Legends Arceus' new 3rd-stage evolution Ursaluna might be just the Pokemon you've been waiting for. There's one small problem, however - actually evolving Ursaring into Ursaluna is incredibly obtuse, and the game never quite makes the process clear.

Thankfully we've gone through the trouble ourselves, and we're more than ready to relay the steps necessary to get your grizzly new friend. As with our guide on evolving Basculin to Basculegion, we go step-by-step, starting with catching the baby form of the trio, Teddiursa, and then evolving and upgrading twice from there. Here's how to get Ursaluna in Pokemon Legends Arceus...

Where to Find Teddiursa

Technically you can find Teddiursa on a handful of the game's maps - but the earliest, and by far the easiest to deal with, is an easily accessible Teddiursa spawn location in the Crimson Mirelands.

Find this valuable spawn zone just south of the main campsite, to the west of the Gapejaw Bog, you'll find a permanent spawn location for a ton of Teddiursa and an Alpha Ursaring, if you'd like to test your luck. 

If you're weaker, you'll probably want to be careful around this site to Lure the Teddiursa without getting the attention of their Alpha sibling. It's almost impossible to miss this group of ursines, but we've left some screenshots showcasing their location below either way:

Where to Find Peat Block

This is the first wrinkle you'll have to face in your quest to get your Ursaluna is getting hold of a Peat Block, an Item thjat compromises another one of the Evolution Methods in Pokemon Legends Arceus.  Peat Blocks are a unique evolutionary item, much like the Black Augurite needed to evolve Scyther into Kleavor, which is not available at the Merit Points Item Exchange.

You technically can get one as a reward for Request #86, but that would mean waiting until you've reached the game's last area. On the flip side, you can actually find Peat Blocks with a relatively high spawn rate by using the Ursaluna mount, with its treasure tracking.

Your other option would be hoping that a Space-Time Distortion drops a Peat Block for you to use, so I would advise going digging for one instead.

How to Evolve Ursaring into Ursaluna

Setting aside the necessity to evolve your Teddiursa into an Ursaring - if it's not already a high enough level to evolve upon capture, it won't take very long to get it there - the real complication comes once it is time to evolve your Ursaring into Ursaluna.

You see, the Peat Block won't work on your Pokemon unless it's nighttime, with a Full Moon. If you're lucky, you'll get a Full Moon on your first attempt - but if you need to, you can simply rest until nightfall at a camp to push the game forward a day. The moon does follow a consistent lunar cycle, so even if it might take a while for it to wax to the right size, you won't be at the mercy of random chance to evolve your Ursaring.

Once it's a full moon, the Peat Block will list itself as "Compatible" with your Ursaring, and before you know it you'll be the proud owner of an even grizzlier bear!
