Queen's Domain weapon evolutions are what happens at level 10: weapons carry their own level, separate from your character level, and most of them change into a different weapon with a new secondary attack. Every level adds 3% damage, and that bonus is capped at 30%.

How Queen's Domain weapon evolutions are earned
Weapons gain experience from the damage they deal, not from the number of swings. A charged hit on an enemy that is weak to that weapon's damage type levels the weapon far faster than a string of light taps, so fight skeletons with the club and plant enemies with a blade rather than mashing one weapon at everything.
Spirit Oil is a consumable that adds weapon experience to whichever weapon you are holding, roughly a couple of levels per bottle. Use it on the weapon you actually plan to evolve instead of the one you happen to be swinging.
The best weapons guide explains which weapons are worth the grind.
The eight level 10 evolutions
| Level 10 weapon | Evolved weapon |
|---|---|
| Rusted Short Sword | Sipeha's Twisted Heart |
| Rusted Spear | Jigeki's Serpent Thrust |
| Wooden Club | Puwema's Blessed Orb |
| Rusted Greatsword | Wodaso's Holy Lightning |
| Rusted Great Morning Star | Jigeki's Rot |
| Rusted Leaf Blade | Puwema's Wind Dancer |
| Rusted Longhammer | Sipeha's Void Maul |
| Rusted Greataxe | Okbujo's Silver Garden |
Three of the changes are worth planning around. Sipeha's Twisted Heart is a 14 Power physical blade that nothing resists. Jigeki's Serpent Thrust has a charged strike that poisons and briefly stuns. Wodaso's Holy Lightning is an area blast for rooms full of enemies, though it stays slow.
Evolving a rusted weapon also leaves a plain copy in Umbada's stock: Common Spear, Scaled Greatsword, Bronze Great Morning Star, Gilded Leaf Blade, Silver Longhammer, Black Steel Greataxe, Ancient Short Sword and Hard Wooden Club. If you are not sure you want to give up the original, you can pick up the same weapon again after the evolution.
The weapons that never evolve
- The Cestus, the Diamond Blade and the Engraved Halberd never evolve, though the Cestus has a separate later upgrade path.
- The Trident breaks at weapon level 5 and leaves the Trident Key behind.
- The Reinforced Jar Club breaks at weapon level 5 and leaves the treasure Symbol of Jigeki.
- The Pandora Blade never evolves and has no level 10 cap at all.
Two of the eight base weapons are secret. The Rusted Longhammer sits in a hidden room below the Neasied cemetery, and the Rusted Greataxe is behind the hidden wall on the long spiral staircase in Deimpo Mausoleum, near Chef Gagi.
The Pandora Blade guide is the clearest example of a 5 Power weapon that is still worth carrying.
Past level 10
Ten Data Modules are hidden behind orange symbols around the island. You open them with the Orange Ochre Seal Breaker that Ossi gives you, then hand each module to Mechanical Engineer Ossi in the Ancient World, where every module fills one of twelve slots in his powered suit. A weapon must already be at level 10 before it appears in the upgrade list, and upgrading every main weapon completes the Perfected Weaponry set.
The Holy Sword Endu has its own path rather than a level 10 evolution. Take it to level 10 to turn it into Soul Bound Endu, level that to 10 again, and then reforge it at the Altar of Purification in Verdant Hollow with all five Wind Gems and the Storm Gem in hand.
The Holy Sword Endu guide covers the reforge that takes the sword past its normal cap.
Getting the weapon list right
Weapons that evolve are worth taking as soon as you find them, even the weaker ones, because the evolution at level 10 is a free upgrade rather than a hunt. The Rusted Short Sword, the Rusted Spear and the Wooden Club are all given or found in the opening area, so they are the first three you should push to level 10.
