You can socket gem into your equipment. The gem’s shape must match the equipment socket in order to equip them. Once you equip the gem, you can power up your gem directly (so you don’t need to wait or remove the gems before powering them up).
Gems have 5 shapes, each of them has 3 different colors which make 15 variation. You can see them on the picture below.
Here is the explanation about each attribute
|ATK||Increase damage and healing|
|Def||Reduce damage inflicted|
|HP||Increase your health|
|Speed||Skill Cool time and priority|
|Accuracy||Increase successful attack (bad status if the chance is not mentioned on the skill description; such as Miho’s burn)|
|Evasion||Increase your evasion against normal attack/ bad status|
|Penetration||% if ignoring enemy’s defense when attacking|
|Crit Rate||Increase chance to inflict critical damage|
|Attribute Res||Decreases damage cause by stronger attributes (ex: decrease damage from fire hero when you are an earth hero)|
|Attribute Up||Increase damage when attacking weaker attribute enemy (ex: gives bonus fire damage when attacking earth enemy)|
|Revive||Recovers HP each wave/round|
|Recover||Recovers more HP when healed. Ex: if you have recover +10%, then healing spells that have 1000 power will heal you for 1100 HP|
|Crit Dmg||Increase damage cause by critical attack|
|Crit evasion||Increases evasion % from critical hit.|
|Crit Def||Decreases damage from critical hit|
I will make a hero review which will cover which type of gem that you should equip on the particular hero, visit the main page to see the list later :).
There is also a special type of gems called rainbow. You can’t equip them, but you can use it to power up any gems.
Like hero, you need to power up the gems to make them stronger, it takes 4 gems of the same level and same shape to produce higher level gems (color doesn’t matter). Below is the cost and the amount of lvl 1 gems which are needed
|Upgrade from||Upgrade Cost
|Lvl 1 Gem needed|
|Lvl 1 to 2||1,000||4|
|Lvl 2 to 3||3,000||16|
|Lvl 3 to 4||8,000||64|
|lvl 4 to 5||20,000||256|
|lvl 5 to 6||50,000||1024|
Below is the property of the upgraded gem (It’s not complete yet, if you have the data please leave comment so I can update the table)
|Shape||Attribute||lvl 1||Lvl 2||lvl 3||lvl 4||lvl 5||lvl 6|
At level 6 the gems also gain additional random effect (become legendary gem). So, make sure you make the gem into legendary ASAP.
The best way to obtain gem is from the abandoned mines. The maximum gem’s level obtained from abandoned mines are depends on the depth. Example: At B3 the maximum level of the gem which you can obtain is 3, etc. However you can still can get lvl 1 gem even if you farm on the B6.
This is when a hero such as Miss Cheery and Giants are really useful. I will create a video guide later, so you have an idea how to pass the level.
I think those are all things you need to know about the gems, if you have more questions. Feel free to ask them on the comment section below.
