Holy Sword Endu: Wind Gems, Air Dash & the True Holy Sword Akunra

Holy Sword Endu: Flying, Wind Gems and Akunra

Updated Nov 2, 2026 · Combat

Quick answer

You get Endu by beating the Shrine Guardian and entering the Endu Shrine (72.3% of players have it). It gives an air dash that carries you across gaps — Ctrl on PC, RB on a controller, even when Endu isn't equipped. Each of the five Wind Gems adds a dash; the Storm Gem unlocks its ultimate. At level 10 it becomes Soul Bound Endu, and one player reports the route to the True Holy Sword Akunra.

Getting Endu

Find the Endu Shrine Key in the Crypt (take the descending branch).
Beat the Shrine Guardian — weak to Impact (bosses).
Take Endu from the shrine. Achievement Flying Sword, 72.3% of players.

The air dash

Endu’s special is an air dash that flings you forward across gaps. You can dash without Endu equipped: Ctrl on keyboard, RB on a controller ✅. Dashing is how you reach most of the island’s secrets.

Wind Gems: more dashes

Each Wind Gem adds a dash, so you can chain longer flights. There are five; the achievement Feel the Wind (all five) was at 4.0% on Nov 2.

Gem	Where (from the walkthrough videos)
2nd	While starting to light the beacons — IJ 58:58
3rd	After Obmuer Temple — IJ 2:08:06, GG 4:07
4th–5th	Later in the game — not documented reliably yet

Some gaps need a set number of dashes: one player notes a fallen knight’s key in Deimpo Mausoleum needs four ⚠️. If you can’t make a jump, come back with more gems.

The Storm Gem: the ultimate

The Storm Gem in the Tower of Knowledge unlocks Endu’s ultimate attack (Raging Tempest, 22.8%).

FAQ

How do I get the Holy Sword Endu?

Get the Endu Shrine Key from the Crypt, beat the Shrine Guardian, then take Endu from the shrine. It's the step where the old demo ended.

Do I need Endu equipped to fly?

No. The air dash works from its own button — Ctrl on keyboard, RB on a controller — whatever you're holding.

How many Wind Gems are there?

Five. Each adds one more dash so you can cross longer gaps. Recovering all five is the achievement Feel the Wind (4.0% on Nov 2).

How do I get the True Holy Sword Akunra?

One player's route: level Soul Bound Endu to 10, hold all five Wind Gems and the Storm Gem, then use the Altar of Purification at the very bottom of Deimpo Mausoleum. It's a single report. The achievement, Blade Bathed in Holy Light, was at 0.3% on Nov 2.
