Get Holy Sword Endu from the shrine beyond the defeated Shrine Guardian. The sword grants Wind Dash and starts with one Wind Gem. Extra Wind Gems expand your movement; leveling the weapon is a separate combat upgrade and does not add dash charges.
Get Endu from the shrine
The opening sequence is shrine key, Shrine Guardian, then the sword itself. Winning the fight opens access, but you still need to walk into the shrine and collect Endu. Check your inventory instead of assuming that the boss automatically added every reward.
Also interact with the defeated Guardian for the Stone Duck Figurine. These are two different pickups with different uses. Before heading into a new part of the island, return to a Crystal Monument and save the progress you have just made.
Wind Dash changes the route
Wind Dash is the movement ability that lets you cross gaps and reach elevated paths. Aim toward the place you want to reach and use the Wind Dash action. Consult your current control bindings for the correct key or controller button rather than treating Endu’s regular attack as the movement command.
The dash remains available after acquiring the sword even when another melee weapon is active. Watch the diamond indicators for available charges and allow spent charges to recover. Test a short, safe crossing before committing to a longer gap with no convenient landing point.
Three kinds of upgrades
| Upgrade | What it changes | What it does not replace |
|---|---|---|
| Weapon experience | Endu’s combat progression and eligible evolution | A missing movement charge |
| Wind Gems | The number of consecutive Wind Dashes available | Weapon damage upgrades |
| Storm Gem | A separate special attack associated with the Tower of Knowledge | An additional Wind Gem |
This distinction matters when a jump seems just out of reach. Spending time attacking enemies with Endu will not by itself solve a crossing that needs another dash. Look for the next movement pickup instead of assuming the gap needs a higher weapon level.
What Soul Bound Endu means
Published launch guides describe Holy Sword Endu evolving into Soul Bound Endu at weapon level 10. Treat this as weapon progression, not a new region key or a way to add another dash. Specific damage totals and combat comparisons are outside this guide’s checked scope.
If an update changes the evolution behavior in your build, keep a screenshot of the item description and the current game version. The in-game result should take precedence over an older table. You do not need to complete the evolution before following the early Wind Gem route.
Your next movement objectives
Head toward the eastern bridge and collect the Azure Torch. Then return to the elevated opening area for the second Wind Gem. The early Wind Gems guide separates the first three pickups and the crossings they support.
The Tower of Knowledge has its own entrance condition involving outdoor beacons. It is not simply a test of whether you have collected every Wind Gem. If you are standing at a sealed tower door, check the tower puzzle guide before searching for an unrelated upgrade.
