Core System

Dragon Raja Walkthrough and Guide by Paul (vhayste)
Thank you for printing this page from to come back to check for updates to this guide and much more content for Dragon Raja
What is the Core System in Dragon Raja? This is a system that’s added in order for you to increase your base stats using elemental gems that you get in the game. Depending on the Gem that you choose, you can increase a specific stat.

Core Page

In order to access the Core page, press + from the main menu and press Core. Here you’ll see an artifact at the front that’s shaped like a triangle.

Accessing Core Page

Each element can hold up to 9 gems. In order to use the Core, you’ll have to choose a side through Quick Select on the left. Once you have chosen the side, you can then socket Gems through the buttons on the right.

Core Overview

Gem Effects

There are different levels of gems, higher levels provide increased stats. Here are the types of gems available and their effects.
Gem Type Stat Bonus Stat Effect
Earth Gem CON Increase HP, PDEF, MDEF, Crit Res
Fire Gem INT Increase HP, MATK, Multistrike
Water Gem INS Increase HP, MATK, AP, CDR
Wind Gem DEX Increase HP, MATK, Crit, Multistrike

Core Mechanics

Here are the core’s mechanics, your aim is to fill up the core with different gems of your choosing depending on which stat you want to increase. Once all slots have been filled up, you need to level up each gem to a certain level in order to unlock the Core Resonance effect. You gain a new Extra Skill, or Weapon effects.

Core Mechanics

Pressing the “View” button on the core page will show you the weapon effects and the required level in order to activate Core Resonance. For example, in this image, all gems that are slotted must reach at least level 10+ to activate the Weapon Effect: River Styx, or reach level 5+ in order to gain increased stats and unlock Ex Tyrant Eye

Core Resonance

Socketing Gems

Once you have obtained a Gem, you can socket it to the Core on the right-hand side. Choose the Side of the core you wish to place the gems into. If you look at the Quick Select on the left side, you’ll see four elements.


If you chose a specific element, you can add more gems of the same element on that side. So if you wish to use Earth Gems to increase your CON, make sure to socket them through the Earth side of the Core.

Gems in place

Strengthening Gems

You can level up Gems by combining them. In order to do this, press a specific gem in its socket and press “Level Up”. The interface will appear and shows you which gems you need in order to continue. Your end goal Is to have each gem that’s socketed to have a high level in order to activate your Core’s Resonance.

How to obtain more Gems

Elemental gems are obtained through the shop, as well as through events and opening activity chests. High leveled ones can be purchased with Diamonds, and you can farm low level ones by gaining Activity points.
