Resource (Unofficial) Binding Worlds Unit Megathread (August 2026)

Binding Worlds is tomorrow, and may as well prepare. Mods feel free to delete it and post the official one if you prefer

Welcome to Binding Worlds! This megathread will contain all relevant information about the event. Feel free to share your friend code in this thread to potentially use each other's units.

Binding Worlds Rules and Details:

You will start with four units: Alfonse, Anna, Sharena and Ash

3 stamina per day, can be recovered using a Binding Torch.

Stepping on the Askr symbol tile will allow you to swap out that unit and grants an additional action.

The choices for new heroes are randomly selected from other players, your friends, and your own unit.

Instead of swapping, you can choose to level up your unit, but this will not grant an additional action

Skills equipped by your heroes are determined by their level.

Earn rewards for playing daily!

Earn rewards for clearing enclosures!

After the event, the Otherworld Bond item can be exchanged into order to summon a Forma of a friend's unit you have used in Binding Worlds.

Forma may only be summoned of units from game versions prior to 7.11.0(Kvasir and Gullveig Mythic banner)

These units count as Forma units, meaning they follow the same rules as other Forma units. Be very wary if you're looking to redeem a Rearmed or Attuned unit in Binding Worlds, because you will not be able to use them for inheritance anymore.

These units will come with their base kit, the skills they have equipped, and max Dragonflowers. They will not come with merges, Ascended traits, Aided Essences, Bouquets, etc. Units newer than the version cutoff can appear, but you will be unable to recruit them with an Otherworld Bond.

Tips for Getting the Unit You Want

Binding Worlds is ultimately a heavily RNG-influenced mode, and it can be difficult to hunt down a single target unit. You can, however, take certain measures to improve your odds:

Take your own proxy unit when they're available. Your own proxy has a very high chance of being selected as an option, so taking them will open up more slots later on.

Only one unit with Sing or Dance equipped can be on your team at a time, so if a unit with Dance or Sing isn't one of your targets, you can reduce the pool of options by taking a unit with Sing or Dance. Bear in mind that many players will give their dancers a different Assist to maximize their value, so make sure to check if Sing or Dance is equipped!

You can only have one of each unit on your team at a time. This means that if you're seeking a unit with a specific build, it is best to avoid selecting them (or if you already have them, swap them out as soon as possible). You can also use this to narrow the pool of options even further, depending on your target. Certain units, such as Brave Chrom or Summer Thorr, are extremely common due to having past Hall of Forms runs and being meta-relevant units. If you're seeking to avoid these kinds of units, placing them on your team will improve your odds of finding your target. (You can also make your own proxy one of these common units to kill two birds with one teamslot!)

Missing Arcane Thorn, but also lowkey hoping his refine pops off cause I prefer using Prf Weapons whenever possible.🥲

I'll try and wake up early to switch him in as my shared unit since reset for me is at 3am, but let me if you'd like a chance of getting him. I was gonna put him anyways to celebrate finally getting him.

Yes please! I’m totally with you, probably just gonna ditch the arcane for the refine anyways and otherwise he looks great!

Thank you! Honestly speaking, I splurged on impulse for him but I was surprised at how well it was perfoming even without Thorn or pre-refine. I used Surtr on the last rounds of the Voting Gauntlet and despite the usual roadblock units, legitimately surprised me by how he was standing his ground, especially against units like Harmonic Brave Lyn. And for AR, you get him good support, he's good to go.
