DragonSword Awakening Secret Costume & Hidden Boss Route

#Quick route

A recent release-build video demonstrates an early DragonSword Awakening secret costume inside a deep underwater chest, with a small hidden boss in a nearby cave. The route depends on preparing food before the dive rather than trying to cross the full distance on the default stamina bar.

Use this order:

1. make the demonstrated egg-based stamina recovery dish;
2. make the demonstrated mixed rice-bowl dish that reduces stamina consumption;
3. assign both foods to quick slots;
4. travel to the dungeon marker shown in the source video;
5. head east, reach the boat and set a marker over the deep-water target;
6. eat the stamina-cost reduction food before the long dive;
7. use the recovery food before stamina is fully exhausted;
8. open the bright chest on the floor of the underwater pit;
9. search the nearby wall for a cave entrance leading to the hidden boss.

The exact map marker and several item names are visible only in the source video's game UI. This page does not invent coordinates from the transcript. Use the video alongside the steps below until the location is added to the site's interactive map.

#What reward is in the underwater chest?

The narrator identifies the reward as Kalien's Great Spirit Vestments. Automatic captions and translated subtitles can mishear character and item names, so confirm the English name on the chest reward screen in your current build.

The demonstrated reward is a costume rather than a combat upgrade. The source describes it as free and obtainable early, but this guide does not claim that it is DLC, permanent account-wide content or available before every story state.

#Before you leave: prepare two foods

The video uses two different effects:

The source presents both effects as necessary preparation for its route. Do not wait until the stamina bar is empty before using the recovery item; the eating animation and remaining travel time can cause the attempt to fail.

For a wider recipe reference, use the Cooking Recipes guide.

#How to unlock the egg recovery recipe

The source demonstrates discovering the egg dish by cooking an egg with the Slice method. It then follows an early gathering route near the city and river to collect more eggs.

Practical steps:

• check the cooking screen for the Slice method;
• use an egg as the principal ingredient shown by the source;
• search the river and city outskirts for egg gathering points;
• gather more than one serving so a failed dive does not force an immediate return trip.

The narrator calls the dish “Egg Renewal” in the translated transcript. Treat that wording as provisional until the released English UI is checked.

#How to prepare the mixed rice bowl

The demonstrated mixed bowl uses meat, fish and rice with the Slice cooking method.

The source route obtains them as follows:

• meat: wildlife near the egg route, with poultry and boar discussed in the narration;
• fish: caught directly in water, with schooling fish shown as an efficient source;
• rice: purchased from a city vendor near a cooking fire.

The transcript is uncertain about whether one specific meat is mandatory for the first recipe discovery. Use the in-game ingredient preview instead of assuming every meat variant unlocks the recipe.

Make several servings of both foods. The source recommends a large reserve, but the exact quantity you need depends on your collected Familiar bonuses and execution.

#Travel to the dive point

The video starts from a dungeon fast-travel point, then travels east until it reaches a boat. From the boat, it places a custom marker over the deep-water target.

Because the transcript does not preserve the dungeon's English name reliably, use reproducible visual landmarks:

• the demonstrated dungeon gate or fast-travel marker;
• eastward travel from that point;
• a boat near the coast;
• a large underwater depression or pit beneath the target marker.

If your route looks different, confirm the current patch and story progress. Do not substitute an approximate coordinate from a screenshot taken in another language or build.

#Diving and stamina timing

1. Eat the stamina-consumption dish before committing to the long descent.
2. Travel toward the custom marker without wasting stamina on unnecessary bursts.
3. At the large underwater opening, point the camera downward and descend toward the center.
4. Watch the active food-buff icon; refresh the reduction food if the effect expires.
5. Use the egg recovery dish while enough stamina remains to finish its animation.
6. Look for a brightly visible chest near the bottom center.

The source uses a mount or Familiar for the approach. Collected traversal bonuses can make the route easier; see the Mounts guide for the demonstrated stamina and underwater-dash progression.

#Finding the hidden boss

After opening the costume chest, do not immediately surface. The video shows a cave-like opening in the surrounding underwater wall. Swim into that opening to reach the nearby hidden encounter.

The narrator describes the boss as level 40 and reports defeating it with a lower-level party. Treat both the level and difficulty comparison as a dated player observation. Team Gear, patch, difficulty setting and execution can change the result.

The video also reports a large ore reward from the encounter. This guide does not publish an exact guaranteed quantity without an independently checked reward screen. Confirm the drops in your own build before planning a repeatable ore farm.

#Failure recovery

If you run out of stamina:

• return with more food servings;
• unlock shared mount stamina or underwater mobility bonuses;
• avoid sprinting or dashing unnecessarily on the approach;
• refresh the reduction buff before it expires;
• consume recovery food earlier;
• verify that both foods are assigned to accessible quick slots.

Back up your route notes and custom marker, since the source does not establish whether every map marker persists across sessions.

#Evidence boundary

The official Steam page confirms cooking, gathering, Familiars and deep-sea treasure as game systems. The exact costume route, recipes used, hidden cave and boss are demonstrated by a third-party release-build video. The route is useful evidence, but item names, percentages, exact coordinates, boss level and reward quantities should be checked against the current English UI and patch.
