Bonesky (Nighttime Form) is the dark/ice version of the standard ice pup, and it is locked behind the in-game clock rather than a quest, an item, or a story flag. It lives on a single snowy ridge above Rosetower Woods in Breezy Plains, it never shows up in daylight, and it is logged separately in the Aniilog as entry No. 42B.
Quick answer: Set the time to night, use the Rosetower Woods teleport point, head north and scale the ice wall, then take the snowy trail uphill to the ridge clearing.
Bonesky (Nighttime Form) spawn requirements
The map entry spells the condition out in a single word under Requirements: Nighttime. Everything else is just preparation for a Lv. 49–51 catch.
- It must be night in-game. The daytime Bonesky is a different form and lives elsewhere.
- Only Rosetower Woods appears as a habitat for this form.
- Wild spawns here sit at Lv. 49–51, so a mid-40s roster will struggle if one fights back.
- Carry Aniipods rated for that band. An Aniipod Mega reads Guaranteed Success at this level.
- Keep stamina up. The climb north leans on Hustle-style sprinting, and the game will tell you when you run dry.
Route from the Rosetower Woods teleport point to the ridge
The spawn sits well above the woodland floor, on a shelf of snow beside frozen water. Once you know the starting point, the walk takes under a minute.
Because the whole group spawns in one clearing, this is also the fastest place to chain catches if you are working toward the Nighttime Glynsera shortcut below.
How to confirm the catch worked
The capture prompt resolves on screen and the Aniimo lands in your roster under Aniilog entry No. 42B, which is a separate slot from the basic Bonesky at No. 42A. If your new catch is filed under 42A instead, you picked up a daytime Bonesky somewhere else, not the nocturnal form.
Nighttime Bonesky stats, trait, and skills
It belongs to the Lumin Stage and deals DPS through both dark and ice typing. Its numbers are modest, as expected from the opening entry in an evolution line.
| Stat | Value | Stat | Value |
|---|---|---|---|
 HP | 71 | P.DEF | 56 |
 ATK | 88 | M.DEF | 57 |
 BREAK | 38 | REGEN | 67 |
| Total | 377 | Mobility | Hustle |
Biting Wind raises crit rate by 15% against targets bearing more than five [Ice Debuff] stacks. The synergy is built into the kit: one Ice Strikes cast gives five stacks, while Boomerang Blade adds further stacks for its duration.
| Skill | Power | EP cost |
|---|---|---|
 Ice Strikes | 55 | 20 |
 Night Slash | 55 | 20 |
 Boomerang Blade | 39 | 20 |
While airborne, Boomerang Blade continuously consumes energy; press its skill button again to bring the blade back. Its innate attack is an ice-element physical melee blow. Fire, wind, and holy deal 1.6x damage to it, whereas electric, water, and ice deal 0.625x.
Nighttime evolution path: Fenrier and Glynsera
The catch and each of its two evolutions share the same time-of-day restriction. Level and evolve it within one night period, or reaching the required level at noon will leave you waiting.
| Stage | Requirement | Cost |
|---|---|---|
| Nighttime Fenrier | Lv. 24, nighttime | None |
| Nighttime Glynsera | Lv. 34, nighttime | Freeze Stone x3 |
The end of the line is a Nova Stage dark/ice DPS with a 512 base stat total, the Ice Tornado ultimate, and Frost Tail Strike, a 60-power, 15 EP flip-and-slam that can spend stacks of [Ice Debuff] for 85% extra damage. There is also a second route to it: catch eight Bonesky in a row at the same Rosetower Woods ridge and Nighttime Glynsera appears there directly at night.
Building Nighttime Bonesky after the catch
To retain this form instead of evolving it immediately, invest Potential development in ATK, the stat responsible for its damage. ENTJ suits this setup because the N letter grants +5% crit rate alongside Biting Wind, while Heartseeker Pendant supports the same crit-focused approach.
Its durability and energy regeneration are both low, preventing repeated skill casts. Place it beside a healer or shielder, and bring allies such as Geoclaw or Stellarys that remove ice resistance so its ice attacks hit harder.
The later Resonance Training levels unlock at higher character levels: character level 55 grants LV 6 for one Omnisource Crystal, while level 65 grants LV 7 for two. Outside combat, Hustle makes it a useful traversal option, especially because Rosetower Woods requires so much travel on foot.
Where to level up near Rosetower Woods
Rosetower Woods spans Lv. 43–50 and contains collectibles throughout, making a Bonesky hunt double as an exploration run. If the team needs some preliminary leveling, the nearby Breezy Plains zones fall within a comparable range.
| Area | Level range | Chests | Lumin amber |
|---|---|---|---|
 Rosetower Woods | 43–50 | 92 | 13 |
 Zephyrus Landbridge | 47–57 | 58 | 6 |
 Russet Highlands | 45–50 | 73 | 8 |
Zephyrus Landbridge also holds six lumin amber across two transporters’ worth of ground, while Russet Highlands leans heavier on chests and pathfinder challenges. Both are close enough to the ridge that a single night run can cover a catch attempt and a cleanup pass.
Rosetower Woods carries six pathfinder challenges and 43 ecological points of its own, so clearing those on the same trip saves you from walking the ridge twice. The catch is the easy part here — the clock is the only real gate.
