Core Keeper

The oracle card deck is pretty easy but time consuming to obtaine.

You need 9 cards and one special object to craft them. note that all the item can be found in less than 5 hours but it's better to find some friend or people to exchance the remaining part that you need or have in discord or in group research if you are on xbox.

First you need the Thread of fate it's the special object that you need to use for crafting the deck. You can find it in a tiny structure name the "thread of fate shrine" in the desert of begining and it only apear one time per world. Once you find this eyes looking scene you will need you hoes do dig up a tile in the middle to obtain it.

Then you will need the 9 cards to complet the full deck :

Aura card : by digging in any digging spot in the grass, clay or stone biome you have 1/25 chance of finding it every time you dig or randomly finding it in a ancian chest but the chance are even lower.

Brilliance card : by breaking any ancien create ( the one that glow in blue) in the stone biome or any ancien structure. This one have a 1/100 chance of dropping every time you break. Note that the 2x1 or the 2x2 create dont drop the card.

Entity card : By killing malugaz the corrupted. You can summon or resummon him using a skull of the corrupted shaman. You have 1/7 chance of him giving is card but it also depend on the difficulty in easy you have 1/14 chance.

Inspiration card : you need to kill some Cavelling Scholar ( the white mage) whitch only spawn in Forlon Metropolis. This is a sub biome that you can find in the sea biome. The ennemys respawn every 7 minute if you are more than 50 tile from the metropolis so kill everyone go to your base and come back. you have 1/300 chance of dropping in easy but 1/100 in hard mod. But you can also find this card in any ancien chest located in the metropolis for a 1/75 chance. So when you are in a here clear the ennemie and grad the chest. you can also find multiple metropolis in your word.

Metropolis card : Buy from the vending machine for 3988 coin. Just like the one above only available in a metropolis. The vending machine spawn in group of two and can be found multiple time in a same word you can mine them and bring them to your base but you need to find one that are ilumated whit blue light (not the grey ) because it's the broken version. So when you find a vending machine check if it's glowing blue and the card should be inside for 3988 coin.

Wisdom card : You need to find a chest in the "city sewers". You need once again a metropolis. The room you are looking for is a room full of water and some path made of stone on the side just like a sewers system. In the middle of this room is always a chest protected by some monster and contain the card. You can have 3 city sewers depending on the random generation and your seed but the card is structure exclusifs loot whitch mean that 100% of the time you will have it and can only be found here. The sewers tend to be in the middle of the city structure so check your map to be sure to have clear all the room.

Now the three remaining are all find in the desert of begining and are call the "god card" this three cards were aded in the 1.0 and are extremely rng dependent and can probably not all be find in the same word.

Radiance god card : you need to dig up in digging spot in the desert of begining. You have 1/50 chance of obtaining it every time you dig and it doesnt depend on the difficulty this time. Digging spot are randomly generated when you enter a chunck so if you do a straight line and they do the same path 16 block to the left or right you should find about 20. Digging doesnt respawn when re-entering a chunck.

Temperance god card : find by fishing in the water of the desert of begining. Their is maybe less than 100 tiles of water in the intires biome but you can bring a bucket whit NORMAL water (any other type of water cant drom the card) and start fishing in it. You need more than 220 fishing power to catch anything in this water and more than 300 if you want to make fish less apear and have more chance of dropping this card. Also dont equip any bait because it will make you catch more fish and you dont want fish here. You have 1/100 chance of finding but it depend of your fishing power and bait that you are using.

Endurance god card : find in charred creat in the molten quarry sub biome in the desert of begining. This card is the only one that can not be find in all world. The reason is simple you need to destroy charred creat and only the tiny 1x1 one. The 1x2 or 2x2 one will not drop the card. Every charred creat have 30% chance of dropping some bug and when it drop an item you only have 0.42% of dropping the card. So you have about 1/312 chance of dropping the card when destroying a charred create. I cant say if it depend on difficulty but i was playing in hard mode and i took me more than 400 create and 7 moten quarry to find this card.

If you can collect all the card just put them all in your inventory and right click or use the Thread of fate to get this item well deserve.

Good luck and good farming.
