Karma is used to upgrade structures and resource nodes in the Village of the Venturer and to synthesize Spheres (Town). The dungeons also provide the most player experience per energy spent.
Karma can be obtained two ways from these events:
Karma is dropped by the enemy during the course of battle. This applies to the Skeletons and their advanced forms, Azrael elite encounters, and the boss.
Unlike the other enemy units, Archangels and Blessed Angels do not drop Karma when they are hit. Instead, they leave behind a chest that contains Karma. The amount depends on the level of the dungeon:
Lv. 1: 700 Karma per chest
Lv. 2: 1,000 Karma per chest
Lv. 3: 2,000 Karma per chest
For the purposes of maximizing Karma, multi-hit units with decent HP are recommended to maximize hit combos, which in turn increases the potential for Karma to drop from monsters, especially the bosses.
Focus on one enemy unit at a time to maximize hits combos (for Karma) and achieve overkill bonuses (additional BC and HC). This way a party can be kept in top form without relying on a healer.
The boss' attacks are only single-target, so the player may get by with only consumable items. A unit with a Healing Brave Burst is still a good backup in case the enemy gets lucky.
It is recommended that a player includes a leader with Leader Skills that affect Karma to maximize Karma-farming potential. Such a leader and a high-hit combo party will make these dungeons trivial in terms of Karma gathering.
Sacred Land of the Souls Lv. 1
Since the boss, Memetes, has relatively little health, it's recommended to maximize the 3,000 Karma earned from it.
Including a leader with a Leader Skill that affects Karma and sparking against the boss with high-hit combos can earn the maximum 3,000 Karma in one round.
This dungeon can yield at least 10,000 Karma, assuming the player gathers Karma from enemy, especially Azrael and the boss, Memetes.
The boss can attack up to three times, doing about 800+ damage with a chance to inflict Curse
The boss also has a single-target attack, World of Darkness, that can inflict over 2,000 damage and Curse. This would equate to over 4,000 damage against a Light unit. This attack can be used multiple times in a single round.
The boss can drop up to 10,000 Karma during battle.
Assuming the player maximizes Karma gathering, this dungeon will yield at least 32,000 Karma, and upwards of 40,000 Karma.
