The Bonesky line is one of the cleanest evolution chains in Breezy Plains. There is no branching path, no hidden quest, and no timed event gate. You raise the pup, hit two level thresholds, and spend a single crafting stone along the way.
Quick answer: Level Bonesky to 24 to get Fenrier, then level Fenrier to 34 and spend one Freeze Stone to get Glynsera. No other condition is attached to either step.
Bonesky evolution requirements
| Evolution | Requirement | Materials |
|---|---|---|
| Bonesky → Fenrier | Aniimo level 24 | None |
| Fenrier → Glynsera | Aniimo level 34 | Freeze Stone x1 |
Both steps share the same unlock rule, which is simply reaching the required Aniimo level. The only material in the whole chain is the Freeze Stone, and you need exactly one of them for the final step. Glynsera is the end of the line, so there is nothing to raise toward after that.
Where to catch Bonesky, Fenrier, and Glynsera
Every stage of the family lives in the Breezy Plains region, and the spawn areas narrow as the line gets stronger.
| Aniimo | Habitats |
|---|---|
 Bonesky | Beast Fang Ridge, Driftwise Meadow |
 Fenrier | Beast Fang Ridge, Driftwise Meadow |
 Glynsera | Beast Fang Ridge |
Because the middle and final stages both spawn in the wild, evolving is not the only way to fill the Aniilog. Catching a wild Fenrier skips the first threshold entirely, and a wild Glynsera skips both of them plus the stone cost.
How to evolve Bonesky into Fenrier and Glynsera
How to confirm the evolution worked
The species name on the creature changes, which is the fastest check. A successful first step swaps the Lumin-stage Bonesky for a Gamma-stage Fenrier, and the second step replaces it with a Nova-stage Glynsera.
The Aniilog is the second check. Each stage occupies its own entry, so the new form registers as a separate record once the evolution goes through. The skill list is the final tell, since Glynsera gains moves the earlier stages never learn.
Stat and skill changes across the line
| Stat | Bonesky | Fenrier | Glynsera |
|---|---|---|---|
| HP | 71 | 86 | 95 |
| Attack | 88 | 105 | 118 |
| Defense | 56 | 68 | 72 |
| EP regen | 67 | 81 | 98 |
| BP attack | 38 | 45 | 53 |
| Magic attack | 88 | 105 | 118 |
| Magic defense | 57 | 68 | 76 |
All three stages keep the DPS role, and the element level rises with each step, from 1 on the pup to 3 on the final form. The skill set barely moves until the last evolution, then opens up.
| Aniimo | Skills |
|---|---|
| Bonesky | ATK, Ice Strikes, Boomerang Blade |
| Fenrier | ATK, Ice Strikes, Boomerang Blade |
| Glynsera | ATK, Ice Strikes, Boomerang Blade, Frost Tail Strike, Ice Tornado |
The pieces are built to feed each other. Boomerang Blade costs 20 EP for 39 power and piles on stacks of Ice Debuff while the blade spins, and pressing the skill button again recalls it. Ice Strikes fires three ice blades for three hits at 55 power and applies 5 stacks. Glynsera then converts that pressure with Frost Tail Strike, a 15 EP move at 60 power that can eat Ice Debuff stacks for extra damage, while Ice Tornado sits at 155 power as its heaviest hit.
Ice attacks deal 1.6x damage to Electric and Water targets, and only 0.625x against Fire, Ice, and Rock, so bring a second element to Beast Fang Ridge if you expect Fire opposition.
Nighttime and Prismana forms of the Bonesky family
The family has alternate forms that share the same stat spread as their standard counterparts, but not the same typing or habitat. The Nighttime versions are Ice/Dark and live in Rosetower Woods, and they follow the same evolution thresholds: level 24 for the middle stage, then level 34 with one Freeze Stone for the final one.
Bonesky (Nighttime) is the Ice/Dark pup, described in the log as a young Bonesky adapted to nocturnal life, with dimmed fur for camouflage and crimson eyes for night vision.
Fenrier (Nighttime) keeps the 86 HP and 105 attack of the standard middle stage, with dark grey fur, a patch of blood-red fur at the tail base, and the same crimson eyes.
Glynsera (Nighttime) closes that chain at element level 3, still Ice/Dark and still found in Rosetower Woods. Night Slash, a 55 power Dark move, belongs to these three Nighttime forms and to nothing else in the family.
Glynsera (Prismana) sits outside the evolution chain. It belongs to the Season 1 Keepsakes group, types as Ice/Holy at element level 4, and is the only form in the family with Prismana Slash, a 20 EP Holy move at 55 power that fires three light blades.
Whichever version you raise, the plan stays the same. Bank a Freeze Stone early, keep the pup in your active rotation through the twenties, and you will reach the final stage without ever having to detour for a special condition.
