Blood crystals are a form of currency in DHM. They can be obtained by completing missions, from the gem finder, or from donating (must be unlocked).
Blood crystals are used mainly for buying things from the blood crystal shop. Such as bigger inventory storage, farming patches, and xp bonuses. Blood crystals can also be used with the Time Machine to instantly advance in-game time.
Below are all the places blood crystals are used.
(Note: In this section, BC is sometimes used for Blood Crystals)
Blood crystal well Edit
The blood crystal well allows you to gamble away blood crystals in the hope of getting more. The minimum amount of blood crystals you can throw in the well is 100. (Or if the max is 50, then 50) For more information see the page on wells linked here:
Time machine Edit
The time machine uses blood crystals to run. You may put in any amount of blood crystals in order to advance in game time. The more blood crystals you use, the more time is advanced. For more information, see the link below:
Area Maps Edit
For 500 BC, you can buy the map to the next area. To access this option, hit the locked next button in the exploring area selection area.
Charging an Hp Emblem Edit
So far, the only hp emblem that needs to be charged is the one found in the regular chest. It can be charged for 250 BC.
Blood Crystal Shop Edit
Blood crystals are mostly used in the blood crystal shop. Here are the different upgrades and items you can buy. Since there are seperate shop tabs, the underlined headings are the tabs, and regular headings are the items.
Increases amount of stuff you can have, see link for more info. These upgrades are permanent.
Hp Emblem Edit
Adds 10 to your explorer's max health. This is permanent, and can only be bought once.
VHW spell Edit
changes the wind to very high for 5 mintues, which increases sailboat loot

Woodcutting/Farming patches Edit
Unlocks the next woodcutting/farming patch. These are permanent. See their skill pages for more details. Prices will vary.
Wise Investing Edit
Blood Crystals are hard to get without dropping a few bucks, so this section tells you what is worth it, and what isn't.
The higher it is on the chart, the more important it is you get it first.
This section is based on opinion, but is helpful advise. You can decide to listen to it or not.
|Item or Upgrade name||Price||Wise Purchase?||Why?|
|Capacity||Varies||Yes||You will need more ores and oil as you get further in the game. Without upgrading capatcity, you can't make or use certain items, like the rocket.|
|Hp Emblem||1,000shop,250charge||Yes||You will need more hp to battle higher level monsters|
|Patches||Varies||Yes||The only reason hp emblems is above this is these aren't nessisary, but are really helpful|
|Empty Orbs||Varies on type and amount purchased||Yes||While expensive, these are permenate buffs, and are the best of the consumable items options for Blood Crystals. Plus, you get to choose which buff you want.|
|Enriched Potions||Varies on type||Maybe||These potions are powerful, and can be profitable, but RNG is still a factor.|
|Area Maps||500||Maybe||Just like Gems below, you can get these elsewhere, by exploring the highest area you have. RNG just has to be in your favor.|
|VHW||250||Maybe||If you need energy and have the sailboat, you can send it out while it's active to get more fish. Also helps freinds and others on the server.|
|Mystery Gems||Varies based on amount purchased||No||You might be tempted at lower levels, but you will have plenty of shappires and emeralds, and you can get these boxes as a loot drop in desert.|
|Blood Crystal Well||User chooses||No||There is no gaurentee you will get anything out of this, this is gambling, and is not a wise option.|
|Time Machine||Varies based on time skipped.||No||This is in my opinion, the worst way to spend Blood Crystals. This is an Idle game. You can wait a few hours.|
Notes on the Chart Above: Edit
These are some more reasons I* made this chart the way I* did.
- While VHW increases the fish caught, it still has a high use of RNG, meaning you can still get a bunch of low level fish.
- Patches can help raise the Farming and Woodcutting skills a lot faster, and are permanent.
- I mainly said permanent upgrades are the best, since they keep on giving.
- The Blood Crystal Well is above time machine because you can still get stuff from it.
- Mystery Gems can be sold to the shop for coins, making it the most direct way to convert Blood crystals to coins, but this is not recommended.
- Buffs are not included because they involve spending money, and I* have not done so, so I* can't advise you about it. It's entirely up to you.
If you disagree with the chart above, please comment below, and state why.
- Blood crystals used to be tradable for a few hours on the 18th February
- The Vhw spell used to cost 500 blood crystals
- Instead of buffs, there were two temporary upgrades. These are the +25% xp and 12 hours offline time upgrades, costing 500 and 100 BC respectivley, and each lasted for 7 days.
