When you create a new world with this mod installed, you will start the game in the evening.
Due to the difficulty of starting the evening, you will receive some basic items. (Wooden Sword, Pickaxe, Axe, Dirt Blocks (21), Torch (4), Date (4) and Water)
You have to find a place to spend the night and find something to eat until sahur time. If you can't find much food, you can eat the Dates you have. (I suggest you save one Date to make a Date Sapling.)
You can see the Clock HUD and the Thirst Bar in the lower right corner of the screen.
The morning prayer will be play at 05:00 and the evening prayer will be play at 20:00.
Eating and drinking water while fasting is prohibited. If you eat food or drink water, lightning will strike your head.
While fasting, you will be thirsty and your thirst bar will decrease. When it goes down to zero, you will get the Slowness effect. You can fill your thirst bar by drinking a bottle of water. (Some days you may not be very thirsty, but some days you may be extremely thirsty, so make sure to drink water at sahur.)
Your hunger bar will not be refreshed when you die. Thus, the fasting mechanic will continue when you die. (If you die with a hunger bar of 2 or less, you will start with 2 hunger bars. Hunger bars with fractional and odd numbers will be rounded to even numbered bars such as 2-4-6-8 and 10. For example: If you die with a hunger bar of 3.5, it will be rounded to 4. If you die by the hunger bar of 7, it will be rounded up to 8.
There are bakeries in the form of bread that you can rarely find in the Plains biome. If you find these bakeries, you are lucky because there is a field of wheat to plant in the garden and pots to grow dates. Inside the shop, there is a Stone Furnace you can use and a baker where you can buy (with Blessed Diamond Block) Enchanted Ramadan Pita.
To grow your own Date Palm Trees, you need a Large Flowerpot.
You must first place a Dirt Block in this Large Pot and then put the Date Palm Sapling on it. You should also water this tree with a bucket of water. After you have done all this, you will have a Fruited Palm Tree. To collect the dates you have to right click with Shears and cut them. (You get 4 dates at a time, and sometimes the date sapling may dropped.)
To make your own Stone Furnace; you need Bricks. You can make this Stone Furnace and cook Ramadan pita in it. First, you have to make the Ramadan Pita Dough. Then you have to put it in the Stone Furnace and set it on fire with a Flint and Steel. In seconds, your Ramadan Pita will be ready.
If you want, you can also do Ramadan Drumming. You can make a Drum using a note block and planks, and then combine a stick and a leather to make a Drumstick. Take the drum in your left hand and the drumstick in your right hand and right click. The drum will start playing. Be careful! If you don't play the drums towards sahur (between 3:30 and 4:00), you will lose xp because you wake people from their sleep and disturb them. If you play at the right time, you will have 50% chance to win Blessed Diamonds.
If you want, you can also explode a Ramadan Cannon at the time of Iftar. The recipe for the ramadan cannon is a bit difficult and complicated. Place it somewhere and grab a flint and steel and right-click to explode it. (You must have a fireball in your inventory for it to explode.) If you explode it at the time of iftar (20:00), you will earn Blessed Diamonds. Sometimes you can win a Date Tree Sapling.
Blessed Diamonds are the gem of this mod. It has a power between Diamond and Netherite. Like diamonds, it can be rarely found in mines and can also be earned by playing drums and exploding cannons.
Blessed Armor and Blessed Tools are made from Blessed Diamonds. Their values such as durability, enchantability and damage are slightly higher than diamonds.
You won't lose your sprint ability when your hunger bar drops below 3 while wearing Blessed Armor. Also, when the thirst bar is depleted, the slowness effect won't affect you while this armor is on you.
The Blessed Diamond Sword, burns your enemy for a few seconds on 1 out of 10 hits.
When you mine Emerald, Nether Quartz, Diamond, Coal and Blessed Diamond Ores with the Blessed Diamond Pickaxe, it can drop two gem with a 10% chance.
There is a 2% chance to drop Honeycombs when breaking Oak Trees and Birch Trees with the Blessed Diamond Axe. There may be remnants of bee nests in these trees.
You can make a Ramadan Parcel with Date, Water and Pita Bread and distribute it to the villagers and earn xp. If you put the Ramadan Parcel on the ground and break it, the contents will drop.
