Mining System

Introduction

The Mining System is another good way of earning zeny! You can also receive (by forging) equipment to sell to your fellow bRO players.

Start Mining

1. First, you must purchase the Drilling Boots from David Goldstein in @warp einbroch 50 200. The Normal price of the boots are 500.000.000 Zeny. You may have a chance to get the boots offered by the NPC at 250.000.000 Zeny sometimes.

2. Equip your new drilling boots to gain access to the new mining skills. The first step in the mining process is making a drill.

3. In order to make a drill, you must type in the "whisper" chat box (located on the small left chat box) "npc:mine" with the word "make" (typed on the right long chat box). 

Note: It may take several attempts before you can succeed in making your drill. Keep repeating the process until you successfully made one. Once you have your Drilling Boots and you have created your drill, you will be ready to start drilling..but first, you have to find a mine!

4. You must go to a mining map (which are all listed down below) and to locate the exact spot of where the mine is detected. They are invisible, however. you have a "Detection" miner skill that will guide you on finding the mine's location.

5. In order to detect the mine simply send any message to "npc:mine" - For example, "Drill", "Detect", or.."sdjskja". Anything will work.

Note: The Detection skill will advise you to move up, down, left or right until you find the exact location of the mine. It may take a few attempts before you actually find the mine, but once you do..you can mine it for quite a while before the mine is destroyed.

6. Once you find the exact location of the Mine, you can send any message to "npc:mine" to start drilling into mine and excavating valuable minerals.

Please remember that there's a captcha enabled in mining. It only appears every 10th mining attempt. The answer is already given and you only need to choose the answer from the given choices. If you chose the correct answer, you can proceed normally. If you chose an incorrect answer, you will be placed in a 15-minute cooldown period, and you won't be able to mine for that duration.

7. Once you start mining you will start noticing that the Drill gets hotter whenever you continue to drill on a mine. You must pay attention to the "Heat" in your chat box because if your drill reaches a Heat of 100 the drill, it will break and you will have to create another drill whispering "make" to "npc:mine" (from step 3.).

8. It is recommended that you stop drilling when you reach a heat of 80-90 in order to make sure your drill does not break. It usually takes only a few seconds for the drill to cool down after you stop so you can begin drilling again soon after.

Miner Skill

Whenever you mine you will earn Miner EXP. This experience is used to level up your Mining Skills. Even when you do not find any items in the mine, your miner exp will still increase. The deeper you dig, the more experience you will earn. However, keep in mind that if you break your drill or you move while drilling, you will lose Miner EXP. You can check your current mining level and experience on the message that appears each time you drill.

When you level up, you will be awarded with Miner Skill points. These points can be used to level up Miner Skills that will increase your productivity while mining. You get at a minimum 3 skill points per level, but the number of skill points received may vary depending on your Miner Level.

To view all skills and/or to level up Miner Skills send a whisper to "npc:mine" (small left chat box) with the word "skill" (large public chat box on the right).

Mines Types

There are a total of 8 different mines, all of which drop minerals at different rates. The lower level mines are known for dropping more "trash" items than the higher level mines. It is important to increase your Miner Level so you can gain access to these more productive mines and skills that increase drop rate of minerals. The mines are:

1. Mayan Mine

• Min level to detect: 0
• Distance to detect: 100
• Min level to drill: 0
• Roughness: 12

2. Moonlight Mine

• Min level to detect: 0
• Distance to detect: 80
• Min level to drill: 0
• Roughness: 12

3. Pharaoh Mine

• Min level to detect: 0
• Distance to detect: 75
• Min level to drill: 5
• Roughness: 14

4. Amon Ra

• Min level to detect: 10
• Distance to detect: 35
• Min level to drill: 15
• Roughness: 16

5. Beelzebub

• Min level to detect: 15
• Distance to detect: 10
• Min level to drill: 40
• Roughness: 17

6. Scarabah

• Min level to detect: 20
• Distance to detect: 20
• Min level to drill: 50
• Roughness: 18

7. Valkyrie

• Min level to detect: 30
• Distance to detect: 50
• Min level to drill: 75
• Roughness: 19

8. Addax

• Min level to detect: 50
• Distance to detect: 15
• Min level to drill: 150
• Roughness: 20

Mine stats

1. Roughness: The roughness of each mine influences by how much your drill heat increases during each drill attempt. The range for increase is between the Roughness and Roughness + 4. For example for Pharaoh Mines, your drill heat should increase between 16-20 each drill attempt. Roughness can be reduced by Corrosive oil with every 25 points in it reducing the range by 1.^[1]

Item drop rate formula and Minerals

The followed formula for drop is:

• Mine Name: The name of the mine class.
• Item Name: The name of the item mined.
• Item ID: The item ID of the item mined.
• Drop Rate: The base drop rate of the item, example: 1000/10,000
• Rate Increment: This value is multiplied by the depth. Example: If rate increment is 100 and your depth is 6 the total drop rate will be (1000+(100*6) = 1600/10,000)
• Max: The maximum possible drop rate that can be achieved for that item.

In the example above the drop rate for an item is 1600/10,000. The way the script works is, a random number will be generated from 1~10,000 if the number is less than or equal to 1,600 --> you will successfully mine the item. Otherwise, you will not get any item and will have to keep digging.

There are a number of new minerals introduced that you need to keep an eye for. These minerals will be used to forge new equipment and to fused mvp cards. Here the list:

Mineral	Rarity
Adamite	RARE
Albite	LESS-RARE
Aluminium	LESS-COMMON
Bronzite	COMMON
Calcite	LESS-RARE
Copper	LESS-COMMON
Corundum	LESS-RARE
Graphite	COMMON
Magnetite	LESS-COMMON
Mercury	LESS-COMMON
Onyx	RARE
Silicon	COMMON
Silver	LESS-COMMON
Titanium	RARE
Pure Oridecon Fragment	LESS-RARE
Pure Elunium Fragment	LESS-RARE
Blood Stone	RARE
