Dream Solvent can be difficult to replace when you suddenly need it, which can make using one feel like a bigger decision than it seems.
You may have several Weekly Boss materials you do not currently need, while the material required for a character’s Talent refuses to drop. Converting those materials solves the problem immediately—but should you use your Dream Solvent now, or save it for later?
In most cases, you should use Dream Solvent when it helps you upgrade a character you are actively building. However, spending it on unnecessary conversions or simply reorganizing materials is usually not worth it.
What Is Dream Solvent Used For?
Dream Solvent is primarily used at a Crafting Bench to convert Weekly Boss Talent Materials.
A Weekly Boss can drop several different Talent Materials, and the character you are building may require only one of them. Dream Solvent allows you to convert an unwanted material into another material dropped by the same boss.
For example, if a boss drops Material A, Material B, and Material C, you could convert:
Material A + 1 Dream Solvent → Material B
There is no Mora cost for this conversion.
The important restriction is that Dream Solvent does not allow you to freely convert materials between different Weekly Bosses.
So if the character you are building needs a material from Boss B, materials obtained from Boss A cannot simply be converted into it.
Dream Solvent can also be used for certain Billet conversions. These conversions require 2 Dream Solvents, rather than the 1 used for a Weekly Boss Talent Material conversion.
Should You Use Dream Solvent or Save It?
For most players, the answer is:
Use it when the conversion gives you something you actually need now. Save it when the conversion is only for convenience or preparation.
Dream Solvent exists specifically to reduce the frustration of getting the wrong Weekly Boss material.
If you already have the correct type of boss material sitting in your inventory, there is little reason to spend Dream Solvent just to make your material counts look more balanced.
But if the wrong drop is preventing an important Talent upgrade, using Dream Solvent can save you from waiting for another weekly reset and hoping for better RNG.
That is exactly the situation where the resource is valuable.
When Is Dream Solvent Worth Using?
Dream Solvent is generally worth using when:
- A character you actively use needs a specific Weekly Boss Talent Material.
- You have enough materials from the correct boss, but they are the wrong type.
- The conversion immediately allows you to upgrade an important Talent.
- Waiting another week would meaningfully delay the character you are currently building.
- You have excess boss materials that you are unlikely to need soon.
The key is that the conversion should solve an actual progression problem.
For example, suppose you need one more Weekly Boss material to upgrade your main DPS’s Elemental Burst.
You defeat the boss, but it drops a different material from the same boss.
If converting that drop allows you to complete the upgrade immediately, spending one Dream Solvent is usually a reasonable trade.
When Should You Save Dream Solvent?
Saving Dream Solvent makes more sense when you do not have an immediate reason to perform the conversion.
You may want to hold onto it if:
- You are not currently building a character who needs the material.
- You are converting materials only because you have more of one type than another.
- You expect to build another character that uses one of those boss drops.
- You have very few Dream Solvents remaining.
- The Talent upgrade is low priority and can easily wait.
- You are considering spending multiple Dream Solvents on Billet conversions without an immediate weapon goal.
This becomes especially important when your supply is low.
Dream Solvent is not a guaranteed Weekly Boss reward, so you cannot assume that every one you spend will be quickly replaced. Current reference data lists its Weekly Boss drop chance at roughly 33%, and recent player discussions in 2026 still show significant variation caused by RNG.
Some long-term players accumulate large stockpiles, while other players can go weeks without getting the drops they want.
Is It Better to Save Dream Solvent for New Characters?
Keeping a small reserve can be useful, especially if you frequently build newly released characters.
When a character uses materials from a relatively new Weekly Boss, you have had fewer weeks to accumulate the correct drops.
That makes Dream Solvent particularly useful.
Instead of waiting several weekly resets for the boss to drop the exact Talent Material you need, you can convert the other materials from that same boss.
However, this does not mean you need to hoard every Dream Solvent indefinitely.
Saving 50 Dream Solvents while refusing to use one on a character you are actively trying to build defeats much of the purpose of the item.
Think of Dream Solvent as a backup against bad Weekly Boss RNG, not as a collectible that should never be spent.
Should You Use Dream Solvent for Billets?
Be more selective here.
Converting a Weekly Boss Talent Material requires 1 Dream Solvent, while eligible Billet conversions require 2 Dream Solvents.
That makes repeated Billet conversions noticeably more expensive.
A Billet conversion can still be worthwhile if it directly allows you to forge or refine a weapon you actually plan to use.
But converting Billets simply because you might need a different type someday is harder to justify.
A useful rule is:
Have a weapon in mind before spending Dream Solvent on a Billet conversion.
If the conversion immediately gives you the Billet needed for that weapon, it may be worthwhile. If there is no specific weapon you intend to craft, keeping the Dream Solvent gives you more flexibility later.
Should You Convert Extra Weekly Boss Materials?
Not automatically.
Having 15 copies of one material and only two copies of another may look inefficient, but those extra materials are not necessarily useless.
A future character may need them.
Instead of converting materials simply because you currently have an uneven amount, wait until you actually need the other material.
This avoids a frustrating situation where you:
convert Material A into Material B → later build a character who needs Material A → spend another Dream Solvent converting materials back.
Unnecessary conversions can turn one problem into another.
How Many Dream Solvents Should You Keep?
There is no universal number that every account needs.
A player who regularly builds new characters may benefit from keeping a larger reserve, while someone with established teams may rarely need Dream Solvent at all.
Recent player discussions illustrate exactly this difference: some long-term players report large stockpiles, while others report having none when a new Talent upgrade requires one.
Instead of aiming for a specific inventory number, use a simpler rule:
Avoid spending your last few Dream Solvents on conversions that do not immediately help your account.
Once you have a comfortable reserve, you can be less conservative.
Can You Farm Dream Solvent When You Need It?
You can obtain Dream Solvent from Weekly Boss rewards, but you cannot reliably farm a specific number whenever you want because the drop is not guaranteed.
That is why completely exhausting your supply can become inconvenient.
You might get another Dream Solvent from your next Weekly Boss—or you might not.
This randomness is also why Dream Solvent tends to feel scarce for newer players while becoming much less important for some long-term accounts that have accumulated them over time. Recent 2026 community discussions show both situations occurring.
Final Recommendation
Use Dream Solvent when it solves a real problem. Don’t spend it simply because you can.
If converting a Weekly Boss material lets you upgrade an important Talent on a character you are currently building, Dream Solvent is doing exactly what it is designed to do.
Save it when you have no immediate need, when you are only trying to balance your inventory, or when the conversion is for something you may use someday.
For Billets, be slightly more conservative because the conversion costs two Dream Solvents.
The simplest way to decide is:
Need the converted material now? Use it.
No immediate use for it? Keep the Dream Solvent.
That gives you the benefit of Dream Solvent when bad Weekly Boss RNG gets in your way without wasting a limited resource on conversions you may later regret.
