First off, you'll need to unlock every dragon card, these cards are:
Dragon Ring - Already owned
Dragon Claws - unlocked by "Petward Monk"
Dragon Helm - unlocked by "Petward Monk"
Dragon Shield - unlocked by "Petward Monk"
Dragon Breath (artefact) - unlocked by "Petward Monk"
Dragon Tongue (sword) - unlocked by "Petward Monk"
Dragon Armour - unlocked by "Petward Monk"
In order to get the "Petward Monk" encounter, you have to start from "The Tavern" encounter. In the spoiler below is the whole progression to get to that point:
*** Spoiler - click to reveal ***The Tavern:
*** Spoiler - click to reveal ***Unlocked by Defeating The Queen of Scales
- You first must FAIL, if you get a huge success or success you will not receive the token
- Then you must get HUGE SUCCESS and then ATTACK THE CAPTAIN; if you fail to get these chance cards then you will not receive the token.
-If you pick the wrong card, then immediately go to the xbox dashboard and quit the game. Upon reloading you'll be back before the encounter and can try again.

-there are 2x failure and 2x huge failure chance cards, you need to get a failure or else you'll instantly die.
-Upon surviving this encounter, you'll have all the relics necessary to begin the achievement...

For this achievement I tried Endless, but it took forever to get even half of the dragon relics (potentially due to awful luck, but moving on). So I recommend playing King of Plagues on
Adventurer difficulty
(IT WILL NOT UNLOCK ON APPRENTICE) with this setup:
Equipment Cards:
*** Spoiler - click to reveal ***1 Dragon Tongue
1 Dragon Shield
1 Dragon Armour
1 Dragon Helm
1 Dragon Claws
1 Dragon Breath
1 Dragon Ring
25x random rings (any work)
If not enough rings, then just use other pieces of equipment. I felt more comfortable with only rings.
Encounter Cards:
*** Spoiler - click to reveal ***These are flexible, I focused mostly on cards that I could either pass right over or gain cards from. I avoided combat cards where possible however some are rewarding.
Twisted Canyon is a must: it guarantees you get the sword since it's the only one in your deck.
Blacksmith's Gratitude is helpful if you have the card, pay a little and you can pick an equipment card.
"Shop" is good to add for more chances to buy what you need.
"The Lovers" so you can demand a reward and potentially get 2 rings.
"Captain Boccanera" and "Local Peasant" are decent for revealing the map to save you wasted trips
"Loan" "Angry Guild Master" to get more gold
Other Good Cards, but not all:
Treasure Chest
Dead King's Hall
Lizard Dome
Royal Treasury
Ghost of the Sea (if you already defeated the Kraken at least once before in any playthrough)
While playing, focus on stopping at every shop and don't be afraid to backtrack and hit a shop twice. If you see the Mage's Shop, then you have to stop there until you get the Dragon Ring because that's the only shop that it appears in. Everything else should appear in all the other shops/tinkerers (besides Healer and Priest shops since they don't sell items). If you make it to the floor exit before stopping everywhere, pay attention to what your "Ring of Hindsight" is revealing and backtrack if necessary.
Also pay attention to what cards are being discarded; for example if you landed on "twisted canyon" and got to draw your weapon but it was on the bottom of the deck, the game would discard every card picked before it picked the sword. That would make it so you'd have to wait until your equipment deck was reshuffled before you'd draw the necessary dragon relics from 'gain equipment' cards. If early enough, it might be worth it to forfeit and restart the King of Plagues.
A little bit of luck and patience is necessary. Quit to the dashboard and quit the game to restart it if you ever fail an encounter, die or just want to reload the shops for a better chance at getting the equipment you need. Each run through shouldn't take very long, especially if you skip/breeze past most encounters.
Good luck!!
