Prism Slime Location
To find the Prism Slime, start from the Transit Station in southern Ungien's Circle.
- Teleport to the southern Transit Station in Ungien's Circle.
- Head toward the south-western Lunar Highlands waypoint.
- Use the southern Fast Transit Lane and jump off near the waypoint to unlock it.

Before engaging, equip a team capable of dealing high damage quickly — the Prism Slime has a light-gathering mode that can prolong the fight.
Prism Slime Achievements
The Prism Slime offers three achievements. The first is straightforward, but the other two require speed.
| Achievement | Rewards |
|---|---|
| Defeat Local Legend: Prism Slime. | 20 Primogems, 3 Slime Concentrate |
| Defeat the Prism Slime before it enters its light-gathering mode for the third time. | 20 Primogems, 3 Guide to Moonlight |
| Defeat the Prism Slime before it first gathers light and swells. Ensure it attempts to absorb energy no more than 2 times. | 20 Primogems, 25,000 Mora |
Tip: Use a DPS with high burst potential to finish the fight in two or fewer energy absorption phases. A well-timed Elemental Burst rotation can make this simple.
Mushteshir Location
Mushteshir is found in the Kalag Guarding Grounds, within Ungien's Circle. Reach it by:
- Fast travel to the north-western waypoint in Ungien's Circle.
- Head north-east to find an entrance.
- Enter the north-western passage just beyond a crack in the wall.
- Inside, locate the mechanism and interact with it.
- Complete the intermediate and advanced validation stages, then start the ultimate validation to summon Mushteshir.
Bring your strongest team before triggering the final validation, as the fight is intense.
Mushteshir Achievements
Mushteshir's achievements involve paralyzing it by destroying its detection devices.
| Achievement | Rewards |
|---|---|
| Defeat Local Legend: Mushteshir. | 20 Primogems, 3 Unblemished Lunar Iron |
| Defeat Mushteshir while it is paralyzed. | 20 Primogems, 3 Guide to Conflict |
| Paralyze Mushteshir by destroying all 4 detection devices deployed during its first Suppression Field. | 20 Primogems, 25,000 Mora |
Strategy: Focus on the detection devices as soon as they appear. Use AoE or fast-hitting characters to destroy all four before they activate the Suppression Field. Once paralyzed, unload all your damage.
Tips for Success
- Check your team: Both bosses require high burst damage. Bring a healer or shielder for safety.
- Achievement hunting: For Prism Slime, restart the fight if it enters its third light-gathering mode. For Mushteshir, restart if you miss any detection device.
- Rewards are one-time: These achievements are permanent, so you can attempt them at your own pace.
