Metin2 Mercenary System

Overview

Requirements

The system is available from Champion Level 1. To use it, you must first complete the quest "About Mercenaries". The quest can be started on the Dongan Plains at the Yohara Commander and requires successfully completing a floor in Sung Mahi's Hell Tower.

General

The Mercenary System allows you to send mercenaries on missions to earn passive rewards. To obtain mercenaries, you need to use Merc Licence. Initially you can recruit 24 mercenaries; with Expansion Licences the maximum can be increased to 48.
There are various mercenary types, specializations and abilities, which are described in the next section.
To start missions, you need mercenaries of a certain level and a certain amount of endurance. Endurance can be replenished once per day by defeating enemies when the quest "Deploy Mercs (Repetition)" is active.

Maximum Endurance by Champion Level

Champion Level	From CL 1	From CL 5	From CL 10	From CL 15	From CL 20	From CL 25	From CL 30
Max. Endurance	400	500	600	900	1,200	1,500	2,300

Missions are randomly generated from region, mission type and deployment type (specialization) and can be reset every 24 hours. Up to 6 mercenaries can be sent on a mission at the same time.
After completing a mission, there is a chance that mercenaries return injured. Injured mercenaries cannot be deployed on missions, trained or serve as trainers. They can be restored using the Instant or Slow Merc Heal.

Note The higher your Champion Level, the more profitable the system – CL30 offers 10 mission slots and better rewards.

Mercenary Types

Mercenaries and their Specializations

There are 7 different mercenary types. At levels 10, 20 and 30, mercenaries can receive a random specialization or improve their existing specialization (easy, medium, high). The chance for a specialization or improvement is 50%. The following table shows the different mercenaries and specializations.

If a mercenary has received its matching specialization, its bonus is doubled, provided the mission's deployment type matches the mercenary's specialization.

Name	Spezialisierung	Bonus
Normal	None	No special bonus
Adept	Scout	Increases success chance, reduces mission durationLv. 30 (high): Success chance +5.0% · Mission duration −5.0%
Strong	Fighter	Increases success chance, reduces injury riskLv. 30 (high): Success chance +5.0% · Injury risk −5.0%

Abilities

When recruiting a mercenary, they can receive an ability with a ~60% chance. The strength of the ability scales with the mercenary level, just like the specialization, and increases with each level.
The ability Risky Advantage is twice as likely to be obtained as the other abilities.

Risky Benefits: Increased injury risk but significantly higher success chance Lv. 30: Success chance +9% · Injury risk +18%

Increase Success Chance: Boosts the probability of successfully completing a mission Lv. 30: Success chance +6%

Reduced Injury Chance: Reduces the risk of a mercenary getting injured Lv. 30: Injury risk −3%

Reduce Mission Duration: Shortens the duration of a mission Lv. 30: Mission duration −6%

Extra Champion Level EXP: Provides additional Champion EXP for your character after the mission Lv. 30: Champ. EXP +9%

The probability of obtaining a Teacher mercenary from a Merc Licence is 5%.

Leveling Mercenaries

Mercenaries can be used as trainers to give EXP to other mercenaries. The Teacher mercenary starts at level 30 and can only be used as a trainer. Before training a mercenary you should carefully consider which ability and specialization combination you want. Not every combination is worthwhile and leveling a mercenary to level 30 costs a lot of resources.

Recommendation

Only mercenaries that received an ability when recruiting should be leveled.
As long as you have enough Merc Heal, you should exclusively train mercenaries with the Risky Benefits ability, as it maximizes the success chance.

From level 10, mercenaries have a 50% chance to receive a specialization. Only mercenaries that have received the matching specialization should be upgraded further.
From level 20, the specialization can improve. Only mercenaries whose specialization has been improved should continue to be trained.

Mercenaries that have not received or improved the desired specialization can still be used for now. Once you can recruit enough additional mercenaries, these mercenaries can serve as trainers.

The

Normal mercenaries should never be upgraded. It is also not recommended to upgrade

Lucky mercenaries, as their specialization only affects extra rewards.

Note For a perfect level 30 mercenary with the matching high specialization, you need on average ~1,560 Mercenary Licenses.

Rewards

Every successful mission awards Yang and Champion EXP. Additionally, there are regional chests depending on the map and chests depending on the mission type. The tier of the mission type chest depends on the difficulty of the deployment.

For worthwhile missions, especially from higher Yohara maps, it is worth using the item Legion Commander Essence. Using this item doubles the number of rewards.
