Blue crystal mine

Blue Crystal Mine (Production tile): This tile produces blue crystals continuously. It works the same way as a mana mill;

  • You can upgrade it with red crystals to increase production. The level of the mine cannot be raised above your level in Lost Realm. For production and storage increases see Lost Realm (Blue Crystals).
  • Blue Crystal tiles can be emptied by simply clicking on them, DO NOT waste energy walking to the tile to get the crystals.
  • Blue Crystal tiles cannot be attacked and thus provide you your own steady source of blue crystal income.
Battle altar

Battle Altar – (Dungeon tile) When you have ‘captured’ a dungeon tile you can start drawing resources from them the same way as Blue Crystal tiles, but they cannot be upgraded. At 400 crystals/hour and 4000 max storage their income is pretty big. Battle Altars can be lost to other players after a 4 hour shield expires.

Battle Altars give you more blue crystals than your mines. As you keep expanding your territory, you will see more battle altars owned by different people.

Each battle altar will have a shield or a sword above it. If it has a shield, it is protected. If it has a sword, you can attack their battle altar and take it over.

When attacking their altar, you battle their 5 man line up. It does not take stamina to attack an altar, so keep attacking them until you win

Empty tile

Empty Tiles – All other tiles are empty to have room for the following spawns. Whenever you clear whatever was spawned, a new spawn will appear somewhere else on the map.

Chest tile

Chest or Treasure Box Tile – can be opened with a corresponding key. The chest has 3 different types, it has bronze, silver and gold types of chest. Each chest shown has corresponding keys depending upon the type of chest. The chest opened give different types of Rewards which can be used upon the game features or additional items for every game features like gold and mana and Crests which used for inscription. All items received from Treasure Box goes to Warehouse

Attack monster

Monster Tile – Bunch of enemy heroes: a group of usually 3-5 enemy heroes. Starts off with mainly elites and sometimes a druid or ninja, at level 65-80. Sometimes a group of random 9 heroes in one set of 9 tiles pops out as the level change. Will probably get stronger as world level improves. Beat the enemies in a Torch Battle style fight, where placement is key. Winning will get you some red crystals, some new world exp points, and a random item. This random item can be a key (bronze, silver or gold to open a corresponding chest), a crest bag, or a bag of gold or mana (warehouse items).

  • Monster Tile can be up to 9 heroes. It can be Legendary Heroes mixed with Elite Heroes or even 9 elites (2x Mino, 2x PD, 2x SM, 1x AC, 1x Molta, 1x Cupid) all level 125 (probably higher at later levels)

Energy & Resources


Stamina – You have a maximum of 80 energy. 1 energy is replenished every 10 minutes. You can replenish your energy bar back to full by spending gems; 50, 100, 100, 150, 150 and 150 gems respectively1. Every move on the map takes 1 energy.

  • Every fight takes 6, 9, 12 or 15 stamina (maybe even more later on)
  • Attacking Battle Altar costs nothing
  • When you refill with e.g. 5/80 stamina left, you will have 85/80 stamina (the remaining points are not lost)
  • Gems required to replenish and number of replenishes allowed may vary by level. At level 11, you are allowed 7 replenishes for 50, 100, 100, 150, 150, 200, 200 gems.

Blue Crystals are used to increase the inscription level of your heroes.


Red Crystals are used to increase the production of blue crystal tiles or to combine identical crests from the same level into a higher level crest.


Completing a task upon the Lost Realm grants rewards and achievements too.

Achievementlevel lost realm

Another reward was given as an accomplishments on the Achievements sections where you have to complete set of levels for the Lost Realm. Complete levels gives red crystals, crests and so on as a reward.



Crests are the most important items used for inscribing heroes. Crests has 18 types which corresponds to 18 talents that heroes used. Each crest talent consists of 4 levels. Crests can be combined given that it should be at the same types (ie. 4 level III Slow Down crests can be combined). Crests can be attained as a rewards from each chest opened, monster battle or gained from a Battle Altar.

Tips and Tricks



The goal is to be as efficient with your stamina as possible, since stamina is a very limited and valuable resource. Here are some tips.

  • You need 13 hrs 20 mins to get full stamina.
  • Minimize your movement – Don’t run all over the map because you are using up precious stamina. Let’s say there is a gold chest, but you don’t have a key yet. Don’t even bother going to that space.
  • Don’t waste time and stamina repeatedly battling an enemy you cannot defeat. If you have a hard time with 5 elites, don’t even attempt the group with 9 Legendaries.
  • Mine and upgrade crystal mines from a distance – You don’t need to be on that specific spot to mine it or upgrade it. Simply just click on the crystal mine to gather or upgrade it.
  • Prioritize battling heroes over opening chests – When you keep battling, you will gain levels which further expands your map. As you expand your map, you find more battle altars and crystal mines. Thus the faster you expand, the faster you gain resources, which makes leveling up more important than opening chests. You can always pick up the treasure chests later, especially if they are on the way to the enemy heroes.


  • Currently aquiring blue crystals outpaces your need for them even without leveling your mines. It may notbe wise to use your red gems to level the mines very high, or even at all as your need for red in combining crests will outpace how fast you get them.
  • Sell the blue crystal bags gained from hero combat or chests to get red crystals. Once you start combining crests you will have trouble keeping up with your red crystal needs.
  • If you find you aren’t getting enough blue crystals you can sell unwanted lvl 1 crests for 2000 crystals (lvl 2 = 8000).


  • When you have a large number of bronze keys you should prioritize chests over battle. If you have only a silver or gold chest and no key you can wait and check back periodically until they reset saving your stamina to maximize the number bronze keys you can use until your number of them isn’t excessive. (The resetting of chests and hero groups may work similar to battle altars in that other players may be interacting with ones on your map. It is unsure exactly how this is working currently)


  • Formation is key. Heros that apply coma give you the best chance to win.
  • Putting three heros in your front line will split the opponents focus and speed up the proc of all three of them since they are all being hit. Occasionally the opponent will be too few heros and only two of your heros will have the extra energy gain from being hit. (Immo and TG top and bottom with an atlanticore or other tank in the middle of your front row works well)
  • Pick and choose your battles – Don’t pick fights with an all legendary hero line up if you can’t beat them.


  • If you move to monster (ex: 3 tiles with 3 stamina ) , and pay for monster fight is (ex: 6 for try with 6 stamina ) it’s added as your exp win or lose (3 + 6 = 9 exp added) winning monster also give you level exp
  • Inscribe your most used heroes – Remember, inscribing boosts the stats of your hero. You might as well inscribe the heroes that you use the most in the Lost Realm so you can become stronger there. Inscribing heroes can also strengthen their proc, like Druid, SM, Minotaur, etc
  • Inscribe the same heroes you had uncap first.
  • Start with Druid as he is your Healer and attacker at the same time.
