Crypt

Crypt is a daily event, unlocked at Player Level 21, and it is one of the main sources of Unit Experience and Books. 
Each player can enter the Crypt twice a day.
In addition, players will be ranked on a weekly leaderboard following the total damage dealt, which earns them additional prizes.
=The Event=
# In the Crypt, the higher your player level and the more damage you inflict, the more unit exp you will receive.
# Each player can enter the Crypt twice a day; this resets daily at 05:00.
# Players receive an additional reward if they accumulate a certain number of kills each day. The reward resets daily at 05:00.
# In addition, players who rank highly for the amount of damage dealt that week receive additional rewards. This ranking resets every Monday at 05:00.
# Players can choose to sweep the Crypt and receive rewards based on their highest overall record. Sweeping damage counts for the weekly total damage!
Tip: As your strength grows over time, it is a good idea to try and beat your score rather than just sweeping for a long period.
==Gates==
The first time the player encounters enemies in Crypt, there are no gates (or fences) to protect the units deployed. As one makes progress through the game, gates can be built and reinforced through Privilege, at multiple titles, up to a total of 1024% of initial HP.
==Enemies==
There are 3 types of Undead enemies, belonging to Necropolis. Although, other than Walking Dead the other units are just non-playable units. Each wave will have a different composition:
Unit	Unit 	Description
 	Walking Dead 	A creature that moves slowly and has high attack.
 	Exploding Zombie	Moves quickly, automatically exploding when it comes in contact with the player's fences, causing damage.
 	Ice Zombie 	A zombie covered in frost. It freezes all zombies on the field when it dies.
=Limitations=
# All melee units are disabled. This means you can only use Caster and Ranged units.
# Hero spells deal no damage. This makes heroes like Solmyr, Luna and Sandro really bad* in the Crypt.
*Note that spells are still useful for triggering the Caster Bonus.
Summoned units still do damage but they will die very fast. This includes the Devil summoned by Xeron, and the Azure Dragon summoned by Power of the Dragon Father.
=Strategy=
It is recommended to take the offensive buffs only (for example, spell damage is not needed) from King's Store once in a while to increase your damage record. It is not necessary to do this daily, as the best score will be exclusively taken into consideration when sweeping.
==Early Game==
This is the stage at which you struggle to survive the 1:30 minutes allocated time per Crypt round.
===Recommended Units===
Since your options are quite limited, use the best ranged and caster units you have.
Note that you can take advantage of the stats at the end of the attempt to see which units dealt the most damage.
It is advisable to put your strongest units in the top or bottom row.
===Heroes===
Heroes that buff your units work the best hero. At the beginning of the game, you will probably have only Catherine, but once you unlock Gelu we recommend switching to him.
* Mirth and Slayer your strongest units
* Only use Earth Arrow and Blizzard to slow down near enemies (they will deal no damage). This will help conserve energy for your buff spells. 
 
* Use Frenzy and Precision on your strongest units.
* Only use Stone Skin and Air Arrow when the zombies are nearing your units.
==Mid Game==
Once you can survive for the whole time but are still lower than level 92, you are at this point in the game.
===Recomended Units===
* Budget units:
* More on the expensive or difficult-to-obtain side:
* Pay-to-get only units:
Here are the recommended awakening skills for your units:
*Lich: Choose all awakening skills on the left side.
*Gog: Fire Flood, Red-hot Forbidden Spell, and Magic Weave
*Efreeti: Flame Feaster, Fight in Fire, Magic Weave.
*Phoenix: Blast of the Cross is the most important, the other 2 skills don't matter. Notice that not awakened is not very good in the Crypt.
*Pegasus: Blessing from the Forest, Wild Blade.
Tips:
* Attacking animation of Giant, Storm Elemental, and Beholder are very fast, so they will be your main damage dealers.
* Marksman, Wood Elf, and Orc are not very good because their attacking animation is too slow, so other units will kill the targets before their attack even hits. This means they will do no damage, as you can see in the picture
===Recommended Heroes===
Gelu will be the best hero at this stage.
Recommended Spell Mark: Slayer, Mirth, Bloodlust, Rush Tactic, Fast Attack.
As mentioned before: Giant, Storm Elemental, and Beholder will be your main damage dealers, so use the buff spells of Gelu on them.
===Recommended Set up===
Tips: If you see many units attack a dead unit (this will make them do no damage), try to change the position of those units and find the best setup for yourself.
==Late Game==
This is from level 92 and above, once you get your hands on Dracon (you need to complete Main Story chapter 24).
He will outperform Gelu in the Crypt.
===Recommended Units===
Notice that getting Magog will significantly improve your score. Once again, for awakening skills, choose Fire Flood, Red-hot Forbidden Spell, and Magic Weave for Gog.
The rest of the units remain unchanged from the Mid Game Section.
===Top Unit===
Among all, Dark Elemental is the best unit due to its ability to one-shot entire waves. Once acquiring it from Limited Time Covenant it must never miss from Crypt formation.
===Hero===
Dracon will be the best hero at this stage.
All you have to do is use Clone on Gog and then let them do all the work.
Notice that using Wind Wall on Gog before cast Clone will speed up the movement speed of the clone. This way she will move to the attack position faster.
To further improve your score, you will need to level up ultimate of Dracon and your Gog power until the Clone can one-shot the enemies with a single cast Fire Wall.
After the first clone, you can clone the clone of Gog - this helps avoid wasting movement time.
Furthermore, once acquiring Dark Elemental it is mandatory to Clone it, as no other unit can deal as much damage as itself by to this date.
