Broken Blade Excalibur Guide
Craft the ★★★★ Sword at Jotunheim tower level 3: Sky Key prep, Holy Grail floor bands in Sky Spire, and infusion tips for the forge.
By Bloxron Editorial Team · Last updated
Excalibur is the ★★★★ Sword capstone — forged at the top of the Jotunheim tower, not looted from a world boss. The gate is 100 Holy Grail from Sky Spire, plus the standard Sword piece stack, Fire Seeds, and currency. This guide walks through key farming, floor bands, tower navigation, and how Excalibur fits beside Weapon Ascension without wasting duplicate Holy Grail investment.

Progression Path
Beat Veyrath → unlock Jotunheim ↓ Farm Sky Keys from elemental guardians ↓ Enter Sky Spire — push to floor 41+ ↓ Stack 100 Holy Grails (aim floors 61–100) ↓ Bank Sword Pieces + Fire Seeds ↓ Craft at tower level 3 forge ↓ Soul Forge → optional Ascension
Before You Climb
- Clear Veyrath and reach Jotunheim
- Farm Sky Keys from the four Jotunheim elemental guardians
- Push Sky Spire to floor 41+ where Holy Grails begin dropping
Guardian routes, key drops, and respawn notes live on the bosses guide. Use the calculator with target Holy Grail and quantity 100 to estimate tower clears at your current floor band.
Holy Grail Floor Bands
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
Drop rates on high floors are estimates — push the highest band you clear without failing runs. Floors 101+ shift toward Soul Ore for Ascension-era upgrades; split time only after your Excalibur stack is complete.
Jotunheim Tower Layout
| 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 |
Craft Requirements
- 100 Holy Grail
- Sword Piece I, II, and III
- Fire Seed
- Money and Gems
- Element infusions at the forge (see infusion tip below)
| Infusion tip | Two Holy and two Flame infusions are a common pairing for the finished blade |
Sword piece costs and rarity context are on the weapons guide. Holy Material ore from Jotunheim guardians is separate from Holy Grail — do not confuse the two when planning your stack.
After the Craft
- Forge Master on Muspelheim Island
- Soul Forge levels on Jotunheim tower level 1
- Weapon Ascension and Breakthrough after Soul Forge 12
Breakthrough rolls also spend Holy Grail — finish Excalibur first or commit to Ascension on a different carry before mixing both sinks. Full Soul Forge and Breakthrough detail is in the Ascension guide.
FAQ
How many Holy Grails does Excalibur need?
The Jotunheim tower forge requires 100 Holy Grail. Holy Grails do not drop before Sky Spire floor 41 — plan a key stock and tower time before you start counting toward 100.
Where is the Excalibur forge?
Top of the Jotunheim tower — Excalibur forge station
Which Sky Spire floors farm Holy Grails fastest?
Floors 61–100 offer the best Holy Grail density. Floors 41–60 work for early stacks while your build is still climbing; push higher as soon as clears stay consistent.
Do I need Sky Keys for Excalibur?
Sky Keys — plan a key stock before long tower pushes Stock keys from the four Jotunheim elemental guardians before long tower sessions so a key shortage does not stall your Holy Grail count.
What infusions should I use on Excalibur?
Two Holy and two Flame infusions are a common pairing for the finished blade
Is Excalibur required for Weapon Ascension?
No. Ascension unlocks after Soul Forge 12 on any weapon you keep. Excalibur and Ascension both consume Holy Grails, so finish your Holy Grail target for one path before rolling Breakthrough on another weapon.
