Its free customization alters the core gameplay experience dynamically depending on various factors, such as the player's current level, choice of combat style and weapons, geography and map environment, monsters’ element, and even the weather and time of day. Changing any factor produces a new quest line and outcome, which will change the player's strategy, even when entering the same map at a different time of the day. Players will also find that Core Blaze relies heavily on teamwork. Each instance is designed for teams of up to four players, who will need to instantly react to each other’s combat style in order to achieve the most effective results. However, party modes will allow more than four people to a team.

Core Blaze has also released the four major in-game weapon classes: Sword and Shield, Great Sword, Dual Blade, and Long Bow. Highly distinctive in appearance and function, each of these weapons has its own characteristics and use.

1. Sword and Shield: The Sword is characterized by short range melee attacks, including some defensive moves using the Shield. With this combination, the player will be able to both fend off and heal from enemy attacks.
2. Great Sword: The huge and heavy Great Sword requires the player to utilize both hands in order to deliver the critical blow. With a wide attack area and maximum damage, the player will need to anticipate the possibility of an attack during the weapon’s cool down period. When in a party, this weapon is incredibly destructive.
3. Dual Blade: The dual blade can deliver fast and continuous melee blows to the enemy. But due to the restrictive characteristic of this weapon, the area of attack is small, and merely a single hit isn’t enough to defeat an enemy. A series of successful strikes must be unleashed to bring down foes. When in a party, the Dual Blade is most suitable as the first line of attack.
4. Long Bow: The archer is always an indispensible supporting attack character. Not only can the Long Bow be used in large scale battle, it can be placed on high levels as the secondary line of attack, and cover for teammates in the first line of attack.

The free customization in Core Blaze alsoapplies to weapon choice. Players can freely interchange between different weapons right before combat – Sword and Shield today, Great Sword tomorrow, and then Long Bow strategy in party combat – making it extremely easy to find compatible players to team up with. As each player develops independently throughout the game, their element and characteristics will enhance and influence the performance of each weapon.

Once the player advances to the high level instances, the commonly seen combination of Sword and Shield matched with the Great Sword, or Dual Blade matched with the Long Bow, will no longer become the most viable. Instead, any four random combinations can be created, depending on the instance content, to most efficiently execute the quest and achieve surprising results. Players need to focus on individual advancement and character development to be able to reach the maximum combination potential – yet another of Core Blaze’s unique features.

Core Blaze has more than the typical grind and level system found in most MMORPGs. Players are able to develop their own skills when battling monsters. The combination of the player’s own element, weapons used, geography and weather of the instance, all contribute to the effectiveness of each attack. Instantaneous strikes, attack tempo, angle of attack, and even the compatibility with team members, are critical in achieving success in the game.
