Heroic Mode is a mode where high level players can play significantly more challenging versions of normal dungeons, and acquire rare items and powerful equipment. Upon entering Heroic Mode, you and your party will be placed in a random dungeon (Velder ~ Elysion, excluding Secret Dungeons). Unlike normal dungeons, stamina is not consumed while playing, and you are limited to only 3 resurrections. Mobs and bosses of the dungeons are the same as in their normal counterparts, but significantly buffed, including Absolute Monsters which have even stronger buffs and abilities.
Heroes Assemble Buff
Similar to regular dungeons, players will receive the Heroes Assemble buff when entering dungeons on Heroic Mode through the queue system, which will increase stats in proportion with the number of players in the party. Unlike the normal buff, the Heroes Assemble buff will be weaker in Heroic Mode dungeons.
Heroic Mode Monsters
In Heroic Mode, all monsters and bosses will be stronger than their normal dungeon counterparts. They will have increased offensive and defensive stats and will attack with increased speed.
In Heroic Mode, there will be additional monsters known as Supreme Monsters, which are stronger than normal Heroic monsters. These monsters will possess an attack-type buff from the elixirs that can be made from the Darkness Souls found in Gate of Darkness. These buffs can be transferred to the player if the Supreme Monster is defeated. When the buff is transferred, it will last for 30 seconds. Supreme Monsters will also possess the ability to teleport to the player if they move too far from them.
In Heroic Dungeons, a special monster known as Wimp can appear. They will have a 25% chance of appearing in the dungeon except for the first and boss stages. When the Wimp is defeated, one of the following buffs will be given to the entire party:
Infinite HP for 10 seconds
Infinite MP for 10 seconds
Freeze all monsters for 5 seconds
No cooldown time for all skills except Hyper Actives for 10 seconds
Players will not be able to get the same type of buff in one dungeon.
Heroic Magic Stones
Heroic Magic Stones are drops which can be obtained from running Heroic Dungeons. They can be be used and will grant a random Dual Magic Stones effect. They can be used to craft specific Dual Magic Stones at Glave. They can be obtained by completing the Heroic Challenge and Heroic Advance quests, and sometimes from events.
Heroic Certification is a material required in order to upgrade Dual Magic Stones at Glave, imbuing them with greater proficiency. They can be obtained by completing the Heroic Challenge and Heroic Advance quests, and sometimes from events.
Ancient Iron Stone and Ancient Guardian Stone are materials dropped from running Heroic Dungeons. They can be used in order to craft Ancient Iron Wedges or Ancient Guardian Wedges to increase the number of socket slots on any particular piece of gear.

[Cobo's Adventurer Support Notice] Many adventurers are trying to fight off the demon infected monsters all over Elrios. Cobo is supporting those adventurers by providing weapons.
The events that occur during Heroic Mode are a result of what happened at the end of Lanox's story. After the Demon God Sult was revived by Scar, before the El Lady sealed him away, he was able to plague the land with darkness causing the monsters of all the regions to becoming significantly more powerful.
During the development of Heroic Mode, it had no relationship with Sult. It was based on a unique phenomenon called "Trentay Gas Cycle" (트란테이가스 주기). The Trentay Gas System expands in Elrios every ten thousand years, and it will bring the Shadow World to Elrios. Enemies in the Shadow World are the same as the ones in Elrios, except they're much stronger.
