If you're looking for detailed list of all Wo Long: Fallen Dynasty Dragon Vein Crystal and Essence locations, you've come to the right place. These essential items give you more healing power out of your Dragon's Cure Pot, which acts as Wo Long's equivalent of the Estus Flask.
To increase the potential of your Dragon's Cure Pot, you'll need to seek out the Wo Long Dragon Vein Crystal and Essence locations. A Dragon Vein Crystal, when used, will increase the maximum number of charges you have before you next visit a battle flag – which Souls fans may recognise as the quintessential bonfire. The Dragon Vein Essence, on the other hand, increases how much damage you heal when you activate it. Since it's a relatively difficult games like Dark Souls, you'll want to heal as much as possible with each charge.

Here are all of the Wo Long: Fallen Dynasty Dragon Vein Crystals and Essences:
Dragon Vein Crystal: Two Chivalrous Heroes
After you slay the Zhuyan boss, you'll find a blacksmith named Zhu Xia. Continue on past the zombies and head inside the large building. At the back, there is a chest containing the crystal.
Dragon Vein Essence: The Yellow Heaven Burns
After you place the second battle flag, climb the ledges where the archer is and continue on to find a tiger sleeping in front of a chest that's near the wooden gate and one of the flag placements. It contains the essence.
Dragon Vein Essence: The Valley of Crying Wraiths
After you raise the battle flag that's up a ladder, head down the hill and you should see a Wo Long Shitieshou panda on your right. Continue on to find two tiger enemies. Kill them and claim the item on the ground as your prize.
Dragon Vein Crystal: The Demon Fort of the Yellow Heaven
Upon opening the fort's gate behind the battle flag, turn to the left and beat the ogre guarding the entrance. You'll find the crystal on a bench.
Dragon Vein Essence: In Search of the Immortal Wizard
From the Battle Flag after beating the Zhupolong, which is the alligator-like mini-boss, head to the right and go to the end of the room. Turn left and climb the wall to reach the camp. Turn left and jump across the vines until you reach the essence, which is directly above the Battle Flag.
Dragon Vein Essence: Fall of the Corrupted Eunuch
To find this one, you need to locate the Luoyang Dungeon keys. From the battle flag on the ground floor where the purple water lake is, head inside the cell with many zombies inside close to the flag and defeat them. The key is next to a body near a brazier. To get the essence, go to the opposite side of the purple lake, and just before the entrance to the room with a torch outside, turn left. Open the cell door here with the key and take the essence. The key works on every cell, so don't worry about it being a one-use item.
Dragon Vein Crystal: Fall of the Corrupted Eunuch
When you reach the battle flag just before the boss, head around the right side of the large temple before you and kill both the wolf and the soldier you find here. The crystal is lying next to the bamboo trees on the other side of the tiny bridge.
Dragon Vein Essence: The Battle of Hulaoguan
After beating the corrupted axe-wielding soldier in the side camp battle flag, which is behind you on the side path if you're at the battle flag just before the main fort, hop onto the ballista and fire arrows at the wooden barricade that blocks the path to the chest on the scaffolding ahead. The essence is inside the chest.
Dragon's Vein Crystal: Centuries of Glory Burned Away
From the battle flag in the middle of the lightning dragon gauntlet, climb the barricade and knock down the pot. Jump down, then climb up the rafters on the right. Proceed along the walkway and jump down near the zombies. Climb the walkway at the back and proceed until you can jump across to the square building with the hole in the middle. The essence is down the hole in the middle with a zombie soldier, but be careful of the lightning as you grab it.
Dragon Vein Essence: Darkness Over the Hanshui River
Head to the left from the final battle flag and reach the item at the end. From here, double jump onto the small hut with a balcony to find the chest inside.
Dragon Vein Essence: Tyrant's Final Banquet
After defeating the alligator mini-boss, climb up the rafters and leap to the hanging cage suspended above the water to find the essence.
Dragon Vein Crystal: Tyrant's Final Banquet
As you enter the bamboo garden, jump up the wall to the right. You can also reach the walkway by defeating the axe-wielding soldier guarding the stairs. Once here, walk to the other end of the walkway and just before turning right, leap down the small gap to the left to claim the crystal.
Dragon Vein Essence: Fate of the Entertainer
After you activate the second battle flag, continue past the temple and get to the bridge over the pond with the tiger patrolling the area and a wizard on top. It's at the top of the bridge.
Dragon Vein Essence: War's Flames Blaze Fiercely
After draining the river and revealing the dragon's head, go back to the tunnel of the previous dungeon and turn right when you go to the bottom of the stairs. Defeat the stone statues and go down the now fully revealed stairs to the bottom of the pool. Climb up the other side to claim the essence.
Dragon's Vein Crystal: The Way of the Warrior
Defeat the giant stone warrior and claim the battle flag it's guarding. Inside the temple is a chest that has the Dragon's Vein Crystal.
Dragon's Vein Essence: Lu Bu, Mightiest among Men
After lowering the water level, head to ground level and continue onward, beating the merfolk, until you find a corridor with an axe-wielding soldier, a soldier with a staff, and a soldier with a scimitar and a torch. To the right, there is a shortcut that leads back towards the battle flag before you enter the tower. Go around the corner and turn right, leap over the crumbled building, and head around the dirt path around the building ahead until you find the item on the ground.
Dragon's Vein Essence: Behold the Glaive of Righteousness
During the first half of the level, as you through the foggy area, defeat the first bird enemy, then look to the pond where the zombie soldier is walking to the right of the watchtower. Climb up the battlements near the trees, and the Essence is up ahead.
Dragon's Vein Crystal: Behold the Glaive of Righteousness
During the second half of the level, you'll come across a throne room with a gigantic pig ogre enemy and many archers. Behind it is a stone coffin with a crystal on top of it.
Dragon's Vein Essence: Decisive Battle of Guandu
From the fourth battle flag, which is the one close to the merfolk enemies, run to the other side and climb up the corrupted vines. Follow their path until you reach the door. Open this for a shortcut to the battle flag, then keep following the path until you see the ape-like enemy. Turn right and slay the giant rat as it ambushes you. Instead of heading left, look for a shack to the right. You'll need to jump down to reach it, but the essence is inside.
Dragon's Vein Essence: In The Hidden Village
This one is a bit different from the others in that you need to return two keys to their rightful owner. The first Taoist's key is in the mission 'In Search Of The Immortal Wizard'. You can find it after the fifth battle flag on the green path leading up to the boss. It's on the left next to a stone lantern. To get the second Taoist's key, enter the mission 'War's Flames Blaze Fiercely' and upon reaching the sixth battle flag, the one next to the second stone dragon head leading to the boss, jump down and explore the chamber to the right of the second set of stone pillars you see as you run through the pool. There will be a spider that will ambush you here, so be careful.
Return both keys to the Taoist, who is across the vines from the blacksmith. You need to open the first door before she tells you about a second key, which you can then deliver. Open the second door and turn right, jumping up a ledge and across the gap to finally get the Essence. Incidentally, you need to trade items to the Taoist woman outside the house to get makeshift keys to open them.
Dragon's Vein Essence: The Uninhibited Heart
From the second battle flag, descend into the pit ahead, then turn right. Descend the ladder into the water below and kill the alligator, magician, and zombies. Climb the ladder and walk up to the chest ahead to get the essence.
Dragon's Vein Essence: The Assault on Wuchao
Close to the second battle flag, there's a side room glowing red that's full of spiders. Defeat them and claim the prize inside a chest.
Those are all the Wo Long Dragon Vein Crystal and Essence locations. You should now have a far easier time with the best Wo Long spells to see you through to the end.
