How the sniper loop works
Use Ammo Compression for deliberate burst shots, then reload and reposition. M-9200 rewards compressing at least 10 rounds. Reload before the Marksman's Crank buff expires, and refresh it before entering a boss room.
Prepare the run
Set 20 Wrath and 20 Willpower, then spend the remaining points on Ingenuity. At the Wishing Fountain, take Mysterious Weight and Begonia Sachet. Set the fruit-skewer priorities to 100% Sturdy, 100% Precision and 50% Elemental. Look for Hunter when choosing a Miracle.
Early rooms: finish the Crank quest
Find Stiff Crank early and upgrade to M-9199 at an anvil. Reload 50 times to obtain Marksman's Crank. Use your bound reload action; the author notes G in the video. Group enemies into a line and exploit piercing normal shots. Save compression mainly for bosses until reload equipment arrives.
Mid-run: upgrade the weapon and solve reloading
Take M-9200 at the next suitable anvil. Assemble both crowns and Scythe of Berut while building Sturdy and Precision. Prioritize Crossbow Quiver upgrades and Reloading Wooden Crate: the former shortens reload downtime, while the latter lets reserve magazines supply successive shots. The showcased run reaches Sturdy 10 at 10:33 and Precision 10 at 13:43.
Late rooms and bosses
Once reloading is fast enough, use compression more freely for room clearing. Finish Elemental 6 after the physical and critical core. The author takes Blood of Obrus as insurance against running out of MP in the final fight. For Skeleton's tablet setup, the run takes Rally, combines Rally with Rally, then later combines Harvest with Tri-Head. Keep dodging during boss attacks and fire from safe angles.
What the 100K damage showcase requires
The final check at 18:33 reads 101436 DPS. The author reports more than 10 hours of attempts and spends about 800 Sapphires looking for Haste to reach 140% movement speed for the Dull Resonance Stone quest. Treat that last push as optional optimization, not a normal clear requirement. The final inventory screen shows difficulty 50; this result does not establish the same damage on every difficulty or with an incomplete bag.
Avoid these mistakes
Do not force repeated compression in early rooms with slow reloads. Do not attack the Peddler just to copy the item route: the author nearly dies doing so. Avoid spending rerolls on the final damage record before your main equipment is ready. If M-9200 or the Crank items are absent from your game version, this exact route cannot be assembled.
