All 7 swords: where each one is and when to use it

Sword-by-sword location guide

Each sword below is listed with its confirmed region, route to reach it and best use case. Use this as a detour planner, not a tier list — the right sword is the one that solves your current problem.

• Akai's Greatsword — Region: Dry Canyons opening. Route: picked up at the very start, no detour needed. Use case: the safest all-purpose starter. Clean punish windows, familiar moveset from the Demo. Keep it until a specific boss demands a switch.
• Asteron Meteorrend — Region: Canyon. Route: after the Styracosaurus encounter area, take the upper cliff path instead of continuing on the main road. The sword is in a crystal-lined alcove guarded by two spear-wielding enemies. Use case: wider arc than Akai's, better for multi-enemy clears. Players have reported using it specifically in the DOSEI fight.
• Greybone Greatsword — Region: Grasslands / Jungle Depths. Route: from the jungle center save point, follow the main path past the vine bridge, then take the left fork into the bone-strewn clearing. The sword sits on a pedestal after defeating the Jungle Depths Alpha. Use case: high posture damage, best for bosses that rely on long guard phases (SHIELD, HAMU).
• Noharu Flamborne — Region: Volcanic Chamber. Route: after defeating the volcanic Carnotaurus, return to the arena and take the newly opened hot passage. Pass the heat vents, solve the three-crystal base puzzle (left-middle-right order) and loot the weapon from the central pedestal. Use case: fire-damage scaling, strong against ice-themed late-game enemies. Slow recovery — only use when you know the punish window.
• Ancient Greatsword — Region: Late-game cluster. Route: after the REAPER & SHADE arena, backtrack to the hidden alcove behind the breakable pillar (use Charge Attack). The sword is in a chest guarded by a single elite enemy. Use case: balanced stats, the most versatile weapon for Boss Rush where you cannot swap mid-run.
• Akai Chainbound — Region: Secret boss reward. Route: defeat AKAI TSUKI the Blood Moon (BREAK THE SPIRIT, CLAIM THE STEEL achievement). Use case: the highest single-hit damage in the game, but only obtainable after the hardest fight. Its name is confirmed by launch reviews and player reports.
• Canyon Cleaver — Region: Canyon cliff ledge. Route: from the first Canyon save point, follow the main path until a wide right-side ledge, climb the claw-marked rock and pick up the visible weapon. No combat required. Use case: early reach advantage before the route gets strict; useful for players who prefer spacing over speed.

KASEI weapons (non-sword drops)

• Ankylosaurid Club: KASEI Phase 1 weapon — not collectible, boss-only.
• Giant Cleaver: KASEI Phase 2 weapon — not collectible, boss-only.
• A new weapon appears past the breakable rock after KASEI before the Demo endpoint; exact name needs current build menu capture.

Collection and Boss Rush links

The STAINLESS EXTINCTION achievement confirms a full 7-sword collection target. Boss Rush also makes weapon comfort matter because your choice carries into the mode. Plan your detours around your current boss, not around completionism.
