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

TimeMachine

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:

Wise Investing Edit

Blood Crystals are hard to get without dropping a few bucks. This section is designed to help you decide what to spend the blood crystals you have gotten through playing on.

The higher it is on the chart, the more important (I think) 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. "

It was made by a player who has only used blood crystals from playing the game, so take that into consideration

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 capacity, you can't make or use certain items, like the rocket.
Hp Emblem 1,000 shop, 250 charge 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 necessary, but are really helpful
Empty Orbs Varies on type and amount purchased Yes While expensive, these are permanent 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 friends and others on the server. Also you need VHW for Mission set 23.
Mystery Gems Varies based on amount purchased No You might be tempted at lower levels, but you will have plenty of sapphires and emeralds, and you can get one of this box as a loot drop in desert.
Blood Crystal Well User chooses No There is no guarantee 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.
  • What I have : All capacity upgrades, Hp emblems (1 bought, 1 charged), magic emblems, and some for time machine for quest related reasons. Hoping to get more patches soon.
