Broken Blade Ascension Guide
Weapon Ascension after Soul Forge 12: Jotunheim NPC, Arkenstone and Holy Grail costs, Sky Spire farm bands, Excalibur prep, and Charon Soul Ore routes.
By Bloxron Editorial Team · Last updated
Weapon Ascension is the second power layer after Soul Forge on Jotunheim. Once your main carry hits Soul Forge 12, you can roll Breakthrough multipliers that spike damage, HP, and crit stats — but only if you farm Arkenstone and Holy Grail efficiently first. This guide covers the unlock, tower layout, Sky Spire farm bands, Excalibur prep, and when to pivot to Charon for Soul Ore.
Ascension Overview
| Attribute | Details |
|---|---|
| Unlock gate | Soul Forge level 12 on the weapon you plan to keep |
| NPC location | Jotunheim tower — level 1, next to the Soul Forge NPC |
| Core materials | Arkenstone + Holy Grail |
| Breakthrough range | Roughly 1.1× through 2.0× — higher multipliers are rarer |
| Stat impact | Large damage and HP bumps plus crit chance and crit damage at strong rolls |
Weapon Ascension adds a second power layer after Soul Forge. Breakthrough rolls a multiplier that scales the ascension stat bundle — chase a high roll on your main carry, not on a weapon you will replace.
Endgame Progression Loop
Beat Veyrath → unlock Jotunheim ↓ Farm Jotunheim guardians for Sky Keys + Soul Stones ↓ Push Soul Forge to level 12 on your main weapon ↓ Farm Sky Spire (Holy Grails from floor 41+) ↓ Optional: craft Excalibur (100 Holy Grails) ↓ Talk to Ascension NPC — roll Breakthrough (Arkenstone + Holy Grail) ↓ Push floors 101+ and Charon for Soul Ore
Jotunheim Tower Floors
The tower is your hub for Soul Forge, Ascension, Excalibur, and material shops. Plan which floor you need before burning Sky Keys on unrelated farms.
| Floor | Feature | Notes |
|---|---|---|
| Level 1 | Soul Forge and Ascension NPC | Spend Soul Stones to raise Soul Forge — Ascension unlocks at level 12 |
| Level 2 | Material Shop | Trade Material Pieces for Flame, Frost, Thunder, and other ores |
| Level 3 | Excalibur forge | Craft Excalibur when you hold enough Holy Grails |
| Level 4 | Piece Shop | Buy Sword, Katana, and Buster pieces with Fire Seeds |
Ascension Materials
| Material | Used for | Source |
|---|---|---|
| Holy Grail | Excalibur craft at the Jotunheim tower forge | Sky Spire floors 41+ — rate climbs on higher floors |
| Arkenstone | Weapon Ascension and Breakthrough rolls | Milestone redeem codes and late-game rewards |
Redeem active codes for Arkenstone on the codes page before a Breakthrough session. Full material context lives in the materials guide.
Sky Spire & Holy Grail Farming
Sky Spire runs cost Sky Keys — plan a key stock before long tower pushes. Floors 1–100 for Holy Grail farming; floors 101–200 added with the Ascension expansion
- Holy Grails do not drop before floor 41
- Floors 41–60 — moderate Holy Grail chance per clear
- Floors 61–100 — best Holy Grail density for Excalibur prep
- Floors 101–200 — Soul Ore and other Ascension-era rewards
Use the calculator with target Holy Grail and quantity 100 to estimate clears for Excalibur. Tower rates are marked as estimates — push the highest floor you can clear reliably.
Excalibur Craft (Optional Capstone)
Excalibur is forged at the top of Jotunheim tower — a separate goal from Ascension, but both share the Holy Grail farm route.
| Material | 100 Holy Grail |
| Location | Top of the Jotunheim tower — Excalibur forge station |
| Infusion tip | Two Holy and two Flame infusions are a common pairing for the finished blade |
Weapon stats and infusion details are on the weapons guide.
Breakthrough Rolls
Each Breakthrough spends Arkenstone and Holy Grail to reroll your ascension multiplier. Strong rolls add large damage and HP bumps plus crit chance and crit damage — but costs add up fast if you chase perfection on the wrong weapon.
- Only ascend a weapon you have finished forging and Soul Forge investment on.
- Bank codes and tower mats before rolling — partial stacks stall progression.
- Roughly 1.1× through 2.0× — higher multipliers are rarer — treat anything near the top as a keeper; stop when your clear speed is comfortable.
Soul Ore & Charon (Post–Floor 100)
Floors 101–200 and the Charon encounter extend Sky Spire past the original cap. Soul Ore feeds Ascension-era upgrades alongside your Breakthrough investment — farm it once Holy Grail density on lower bands is no longer your bottleneck.
Charon spawn details, title drops, and farm priority are on the bosses guide. Use the calculator with target Soul Ore to compare Charon against high-floor tower clears.
Best Farming Order
- Finish Yamato or Explosion craft and confirm that weapon is your long-term carry.
- Rotate Jotunheim guardians until Soul Forge hits level 12.
- Stock Sky Keys — do not enter Sky Spire under-keyed for a 100-Grail push.
- Farm Holy Grails on the highest floor band you clear consistently (aim for 61–100).
- Redeem Arkenstone codes, then roll Breakthrough on Soul Forge 12.
- After Ascension basics, push 101+ and Charon for Soul Ore and title farms.
FAQ
When does Weapon Ascension unlock?
Ascension unlocks after Soul Forge level 12 on the weapon you plan to keep. Talk to the Ascension NPC on Jotunheim tower level 1, next to the Soul Forge station.
What materials does Ascension need?
Breakthrough rolls consume Arkenstone and Holy Grail. Arkenstone comes from milestone redeem codes and late rewards; Holy Grails drop from Sky Spire floors 41 and above.
What is a good Breakthrough multiplier?
Breakthrough rolls a multiplier roughly between 1.1× and 2.0× on your ascension stat bundle. Chase a high roll only on a finished carry — not on a weapon you will replace.
How many Holy Grails do I need for Excalibur?
Excalibur requires 100 Holy Grails at the forge on Jotunheim tower level 3. Farm floors 61–100 in Sky Spire for the best Holy Grail density before the craft.
Where do I farm Soul Ore?
Soul Ore drops on Sky Spire floors 101–200 and from Charon on the expansion route. Stack it after Soul Forge 12 while you prep Ascension materials.
Should I redeem codes before ascending?
Yes. Active milestone codes grant Arkenstone — redeem in Settings before a Breakthrough session so you are not short on ascension mats mid-push.
