Finding all 8 Stone Tablets in the Dragonspine region is one of Genshin Impact's many new puzzles. To unlock the sealed door, here is the quickest route to finding all 8 Stone Tablets located around Dragonspine.
Start by fast-traveling to the Teleport Waypoint just northwest of the Frostbearing Tree, then head east toward the water on the outer edges of Dragonspine. The first Stone Tablet will be on stone ruins overlooking the water next to a torch. The Stone Tablet should stand out against other stone structures because of its glowing yellow text.
Next, travel to Dragonspine's Statue of the Seven above the word "City" in Entombed City - Ancient Palace on the map. This Statue requires a new magical resource called Scarlet Quartz in order to unlock if players haven't yet. After locating the Statue of the Seven, head south and jump downwards into the circular ruined structure. Fly into a large stone archway and the Stone Tablet will be just beyond it, sitting next to a button to a large circular door. This is is the sealed door players will return to when completing this Genshin Impact quest, so make sure to mark it on the map.
Fast-travel back to the Statue of the Seven but this time, travelers will want to head south up the mountain rather than underneath it. Climb the ruined stone structures and hug the mountain's edges until another circular door with a cube-like button in front of it. Unlike the last one, this secret room requires three boxes, The Princess, Priest, and Scribe boxes, to unlock. Once those items are found, the Stone Tablet will be inside to the left.
Next, fast travel to the Waypoint northwest of Starglow Cavern and head southeast after getting there. Again, hug the side of the mountain while traveling east until several large crystal-like chunks appear. The Stone Tablet is in this area sitting on top of a boulder, directly above the "o" in Starglow Cavern on the map.
Travel to the Waypoint northeast of Mingyun Village and south of Entombed City - Outskirts. Head east in the space between the two mountains. When the dirt path curves to the left, keep on straight into the trees, then southeast into more ruins. This Stone Tablet requires Scarlet Quartz to get to, which can be found next to these ruins up against rocks. While equipped with it, destroy the magical ice at the bottom of the ruins to find the Stone Tablet.
Next, fast travel to the Waypoint beneath "Wyrm" in Wyrmrest Valley. After navigating south to the circular structure indicated on the map, players will need to complete the Cyro puzzle. The Fire Seelie will indicate which order the Cryo torches need to be lit in while timed. Use Diona if she's been pulled from Genshin Impact's gacha. Then, defeat the ruin guards. Afterward, the circular ice between the Cryo torches will fall and travelers can fly to the bottom level to find the next Stone Tablet on the southwest corner of the circular area.
Fast-travel to the Waypoint beneath "Valley" in Wyrmrest Valley on the map. Following the path, head west and follow the curve around until a ledge appears on the right. Next to a torch will be the seventh Stone Tablet.
Finally, head to the new Domain found at Skyfrost Nail. At the Domain's entrance or fast-traveling to it, the last Dragonspine Stone Tablet will be about 10 feet to the west very close by.
