This page names late-game areas and items. Puzzle answers are folded — open only the ones you need.
The items that matter most: Wind Gems (more air dashes, so more of the map), the Storm Gem (Endu's special), Key Stones (treasure vaults), Seal Breakers (Ancient World and castle doors) and hidden stat foods (permanent bonuses).
Wind Gems (five)
Each Wind Gem adds one diamond to the Wind Dash meter, which is one more air dash with the Holy Sword Endu before it recharges. Players There are five; collecting all of them unlocks "Feel the Wind" (4% of players). Official If a ledge seems out of reach, you probably need another gem. Some jumps that look like they need two gems can be made with one. Players
The Storm Gem
Recovered in the Tower of Knowledge. It switches on Endu's special attack meter. Players It is also one of the requirements for the True Holy Sword Akunra.
Blood and Velvet Key Stones (treasure vaults)
Key Stones open sealed treasure vaults around the island. Exploring every vault is the "Forgotten Rooms" achievement. A vault often contains the next kind of key stone, and one player reports buying their first. Players
Show reported vault locations and lootspoiler
- Blood vault 1: under the Tower of Knowledge, in the caves you reach after clearing the flesh. Loot: Rusted Greatsword, Freshly Dried Herbs, 2 Large Elixirs, Spirit Oil, 5 Ancient Coins, Rejuvenating Water, Panacea.

Mask of Second Sight and its four lenses
The Mask of Second Sight takes four lenses, one for each god: Wodaso, Sipeha, Puwema and Jigeki. "Magic Eyes" (all four) has been unlocked by only 0.3% of players. Official Players
Show where players found each lensspoiler
- Wodaso: a round house on one of the outer islands in the first area. Its key comes from the boss on the Deimpo Mausoleum roof (climb out through the round windows).
- Sipeha: a chest at the Puwema temple, at the highest point of Verdant Hollow.
- Jigeki: dropped by a hidden boss behind the door you open with the tiara puzzle. You need the Jigeki key parts first; one is in the Deimpo Mausoleum spider caves, reached by stepping into the alcove of the rising pillar.
- Puwema: given by Peha.
As reported in "Looking for All 4 lenses for the Second Sight item". Players
Seal Breakers
- Orange (Ochre), Blue and Green Seal Breakers open colored seals. The Ochre one also opens spots back in the starting region, including one near the first Wind Gem. The Blue one is in an Ancient World lab. The Green one is "very high up". Players
- Seal Breakers of Cups, Wands and Swords open doors in Siraatsu Castle. Players found Cups and Wands from a pair of bosses; Swords is past a corridor door sealed with the Wands sigil. Players
Stat foods and the Mysterious Meal
The store page promises you can "eat delicious food to further increase your stats". Official Players report that hidden foods (roast chicken, Steamed Clams, Broiled Meat, the Mysterious Meal and others) give a permanent bonus as soon as you pick them up, and the bonuses stack. Roughly +3% attack speed per Steamed Clams, for example. Players Players
- Many sit behind secret walls. A skeleton pointing somewhere is the usual hint. Players
- Others need tricky dash jumps, like the one out of a Tower of Knowledge window.
- Meal Tickets are a separate quest item for Chef Gagi. See quests.
