Fenrier has two versions in Aniimo, and the Nighttime one is not a skin swap. Nighttime Fenrier is logged separately as No. 43B, carries both the Dark and Ice elements instead of Ice alone, and picks up a control skill the standard Ice form does not use. There are two ways to add it to your roster, and both of them depend entirely on the in-game clock.
Quick answer: Catch Nighttime Fenrier on the ridge north of the Rosetower Woods teleporter during nighttime, or evolve a level 24 Nighttime Bonesky while it is still night.
Nighttime Fenrier location in Rosetower Woods
The pack lives on a ridge in the Rosetower Woods region, and the spawns only exist while it is nighttime. Arrive during the day and the ridge will be empty or populated by the ordinary Ice-element Fenrier instead, so set the time of day before you make the trip.


You are not limited to a single attempt. At least three Fenrier patrol the slope at once during the night cycle, so a failed capture is not a wasted trip.

The second route is the evolution line. Nighttime Fenrier sits in the Gamma stage between Nighttime Bonesky and Nighttime Glynsera, and the form carries through the whole chain as long as the time condition is met.

- A Nighttime Bonesky at level 24 or higher.
- It must be nighttime when you trigger the evolution.
- No evolution stones are needed for this step.
The daytime version of the line evolves on level alone. If you evolve a regular Bonesky, or evolve a Nighttime Bonesky while the sun is up, you get the standard Ice-only Fenrier rather than the Dark/Ice one.
How to confirm you got the Nighttime form
Open the Aniilog and check the entry number. Nighttime Fenrier is filed as No. 43B, directly after the standard Fenrier at 43A, and its element readout shows Dark alongside Ice. The two forms are also easy to tell apart on sight, since the Nighttime version has dark grey fur, crimson eyes, and a patch of blood-red fur at the base of the tail.
The skill list is the other giveaway. Only the Nighttime form runs Night Slash, a Dark-element skill, in place of the pure Ice kit.
Nighttime Fenrier base stats and role
Nighttime Fenrier is a Gamma stage DPS with a medium build, and its mobility skill is Hustle, which burns stamina to sprint. Its base attributes are identical to the standard Fenrier.
| Attribute | Value |
|---|---|
| 86 | |
| 105 | |
| P.DEF | 68 |
| 68 | |
| 45 | |
| REGEN | 81 |

Nighttime Fenrier skills and Biting Wind trait
The kit is built around stacking Ice Debuff and then cashing those stacks in for critical hits. Its trait, Biting Wind, raises the Crit Rate of damage dealt to targets holding more than 5 stacks of Ice Debuff by 15 percent. Its basic attack is a close-range Ice melee swing.

| Skill | Element | EP cost | Power |
|---|---|---|---|
| Ice | 20 | 55 | |
| Dark | 20 | 55 | |
| Ice | 20 | 39 |
Ice Strikes has a 1-second cooldown. Use it to lunge and spin, creating a magic field; the field launches three ice blades that strike three times and apply 5 stacks of Ice Debuff. That makes it the quickest option for activating the trait.
Boomerang Blade throws an ice blade forward that damages everything in range and applies Ice Debuff stacks. The blade drains energy while it spins, and pressing the skill button again recalls it. It also runs on a 1 second cooldown.
Night Slash is the exclusive one. It steps forward and releases three shadow blades that deal damage and silence the target for 4 seconds. The trade-off is the longest cooldown in the kit at 15 seconds, so it is a control tool to hold for a dangerous cast rather than a damage filler.
Evolving Nighttime Fenrier into Nighttime Glynsera
If you are chasing the Nova stage, the next step needs a Nighttime Fenrier at level 34, the nighttime condition again, and Freeze Stone x3. Evolving during the day breaks the chain and produces the standard Glynsera instead.

Nighttime Glynsera can also spawn on the same Rosetower Woods ridge if you catch 8 Bonesky in a row there, which saves you the stones entirely.
Either path gets you the same creature, so pick based on what you already have. If a Nighttime Bonesky is sitting in your roster near level 24, evolving is faster than the climb. If you are starting from nothing, the ridge run is a single trip that can hand you several attempts in one night cycle.
