Elsword is 2.5D action MMORPG developed by the South Korean company KOG Studios. It features real-time action gameplay and includes both player vs. environment and player vs. player modes. There are twelve playable characters within the game, each with unique backstories and distinct abilities. While playing the game is free, some items and costumes can be purchased through an in-game "Item Mall" using real currency.

The story of Elsword takes place in Elrios, a mystical land brought to life through the power of a gem known as the El Stone. When the El Stone is stolen, Elsword and his allies go on a quest to recover it and bring the thieves to justice. Along the way, new allies join his team, known as the "El Search Party". While this story ties the eight regions of the world together, each region has multiple subplots that unfold as players complete the dungeons in that region.

Different types of skills:

Passive - an always-on effect without any mana cost, as long as the conditions are met. 

Active - requires some mana to activate; mana cost and cooldown is very low but does not do significant damage.

Buff - gives the player and allies a special effect or a power boost for a limited time when activated.

Special Active - has a special skill image when activated.

Locked Skills - require completing a quest to be unlocked.

Chain Skill - Exclusively for Ara, she is able to 'cancel' a skill and resume it with another skill.

Combination Skill - only available for Lu/Ciel. It is a skill that utilizes them both to do a strong attack.

Hyper Actives - strongest skill; may be unavailable on other servers. It is also a locked skill and can be unlocked at level 65.
