Dragon Marked for Death Flags Guide

When I started playing this game I got stuck without new quests for a while and little did I know that I had to complete certain requirements (flags) in certain missions to advance. So, to make things easier for new players I decided to make a guide on how to complete everything single mission with its flag. 

Without further a due here's my Dragon's Marked for Death Flags Guide.

THE OGRE FORT

Go left until you find an old woman and talk to her, she'll tell you about her son. Keep going left until you're stopped by two yellow goblins, kill them and they'll drop a chest with a pendant. Return to the old lady and give it to her then you can proceed with the rest of the level.

SEA OF TUMULT

Go inside the ship to find a man locked behind a door, talk to him and then grab the key on the lower floor. After opening the door talk with him again and he'll tell that he'll reward you afterward. Proceed with the level until you're inside the monster and, yet again, talk to the man, you can then finish the level as you please.

THE FRIGID NEST

Play the level until you enter the cave, inside you'll want to reach the upper level. To reach it you need to take the elevator on the image below and be sure to step on the switch beforehand to call it.

Keep going up and enter the cave again, after running through it for a while you'll find a Divine Knight. After beating him you can finish the rest of the level.

UNDYING DRAGON

First, defeat all monsters and then escort Eterno to its cabin, then keep talking to him until he repeats the same sentence.

UNEARTHED ROYALTY

Play through the level until you reach the chests. On the lower floor proceed to the right past the warping gate and defeat all the enemies that appear and then step on the switch. Trackback a little until you reach the passage that was being blocked. Defeat Vasith and read the text on the wall.

THE CASTLE BURNS

After entering the castle through the sewers run through the middle section where you'll find these wooden floors. 

Destroy the third one and you'll have access to a hidden boss fight. Defeat it and proceed with the level.

CALAMITY'S PROTENT

Just defeat every enemy in every single gate, simple as that.  

TRUTH IN HEAVEN

After riding the second elevator keep going up through the right until you reach a part with a switch on a platform. Step on the switch and climb the disappearing platforms. At the top read the text on the wall and proceed to finish the rest of the level.

And that's all! I hope you find my Dragon Marked for Death Flags guide useful! If there's something you don't understand just ask!
