Blazamut Ryu Slab Fragment

Details

It weighs almost nothing and stacks to 9,999, so there is no reason not to carry a full stack. It sells for almost nothing, so do not bother hauling it to a shop.

Where to Find Blazamut Ryu Slab Fragment

Blazamut Ryu Slab Fragment shows up as world loot — chests in the Snowfields, chests in the Sakurajima and chests in the Feybreak, and 10 more pools besides, usually 1–2 at a time. Higher-grade chests carry the better rolls, so the ones guarded by a camp are usually worth the detour.

Sending a team on the Astral Frost Cavern, Celestial Sakura Cavern and Dark Cave of Feybreak expeditions brings some back without you leaving base, and 4 more expeditions can return it too.

Seven expeditions can bring fragments back, and they are nowhere near equal. Astral Frost Cavern is the one to keep a team on: the fragment is the heaviest entry in that mission's payout pool, close to half of it, the run is 60 minutes, and it asks the lowest party strength of the seven at 286,000. Celestial Sakura Cavern, Dark Cave of Feybreak and Sunreach Isle each weight it near a third of their pools, at 375,000, 476,000 and 589,000 strength — those are for the second and third teams once the first is out. The bottom three are traps: World Tree Subterrenean City Ruins wants 851,000 strength for about a tenth of its pool, and PIDF Illegal Factory and Moonflower's Secret Hideout both want 1,600,000 and run 120 minutes for no better weighting. Any of them returns 1 or 2 when the fragment is what comes up.

Collecting four is not the only way to reach the summon. The finished Blazamut Ryu Slab drops whole out of the technology-book stands inside Cherry Blossom Cave on Sakurajima, roughly a 25% chance on each grade-5 stand, which is far better odds than any single fragment source. Clear that cavern first and treat fragments as the fallback for the runs where the slab itself does not turn up.

Using Blazamut Ryu Slab Fragment Well

Four fragments buy one Lv 55 Blazamut Ryu at a Summoning Altar, and that fight is the last time you have to pay. Every clear hands back a Blazamut Ryu (Ultra) Slab, along with 2 to 4 Ancient Civilization Cores, 5 to 7 Training Manual (XL), a Dragon Skill Fruit: Beam Slicer and your pick of an Applied Mining, Lumbering or Gathering Handbook I. The Ultra slab summons the Lv 80 version, and that fight also returns an Ultra Slab on every clear — 10 Ancient Civilization Cores, 10 Training Crystals and the Horns of Supremacy with it. So the fragment grind is a one-off entry fee into a loop that then feeds itself, and the Ultra slab's own 500,000-work recipe is a build you should never need to run.
