Aniimo: How to Get Bonesky Nighttime Form in Rosetower Woods

Bonesky’s Nighttime Form is a dark/ice DPS Aniimo that never appears in daylight. It occupies a single ridge in Rosetower Woods, and the only gate on it is the in-game clock — no quest, no item, no unlock.

Quick answer: Wait for nighttime, teleport to the Rosetower Woods point, head north up the ice wall, and follow the snowy path uphill to the ridge clearing where Bonesky (Nighttime Form) spawns at Lv. 49–51.

Bonesky Nighttime Form spawn requirements

The Aniilog entry lists a single habitat, and the map screen spells out the condition in one word: Nighttime. Check these before you travel.

Time of day must be night. The daytime Bonesky spawns elsewhere and is a different form.
Rosetower Woods is the only habitat area for this form.
Bring Aniipods rated for a Lv. 49–51 catch — an Anipod Mega handles this range comfortably.
Keep stamina topped up; the climb north uses Hustle-style sprinting.

The map entry for this form shows the Rosetower Woods habitat as a Lv.49-51 band, so a mid-40s team will be outmatched if a wild Bonesky decides to fight back.

Route to the Rosetower Woods ridge

The spawn sits above the main woodland floor, on a snowy shelf beside frozen water. The climb is short once you know where to start.

From the map, choose fast travel to the Rosetower Woods teleport point. If daylight remains, advance time first; otherwise, no spawns will appear.

From the teleporter, run straight north until you reach the ice wall. Climb it. This is the only part of the route that needs a deliberate ascent.

At the top, follow the snowy path uphill with the frozen river on your side. Staying on the path is enough; there are no branching turns to worry about.

Keep going until the path opens into a clearing. Several Bonesky (Nighttime Form) circle overhead here, and a full group can be on screen at once.

Return to human form, then toss an Aniipod. The catch prompt displays the odds beforehand, and at this level range, an Anipod Mega is marked Guaranteed Success.

You know it worked when the capture resolves and the Aniimo is added to your roster under entry No. 42B, separate from the basic form’s No. 42A slot.

Nighttime Bonesky stats, trait, and skills

This is a Lumin Stage DPS with dual dark and ice typing. Its totals are modest, which is expected for the first stage of the line.

Stat	Value	Stat	Value
HP	71	P.DEF	56
ATK	88	M.DEF	57
BREAK	38	REGEN	67
Total	377	Mobility	Hustle

Its trait, Biting Wind, raises critical rate by 15% against targets carrying more than five stacks of Ice Debuff. That pairs directly with its own kit, since Ice Strikes applies five stacks in a single cast and Boomerang Blade keeps adding more while the blade spins.

Skill	Power	EP cost
Ice Strikes	55	20
Night Slash	55	20
Boomerang Blade	39	20

Boomerang Blade drains energy for as long as the blade is airborne, and pressing the skill button again recalls it. Its innate attack is a physical melee strike carrying the ice element. Defensively, it takes 1.6x damage from fire, wind, and holy, and resists electric, water, and ice at 0.625x.

Evolution path: Nighttime Fenrier and Nighttime Glynsera

Both evolution steps carry the same time-of-day lock as the catch, so plan to level and evolve during the same night window rather than hitting the level threshold at noon and waiting around.

Stage	Requirement	Cost
Nighttime Fenrier	Lv. 24, nighttime	None listed
Nighttime Glynsera	Lv. 34, nighttime	Freeze Stone x3

The payoff at the end is a Nova Stage dark/ice DPS with a 512 base stat total, the Ice Tornado ultimate, and Frost Tail Strike, which can consume 10 stacks of Ice Debuff for 85% extra damage. Nighttime Glynsera also has a second route: catch eight Bonesky in a row at the same Rosetower Woods ridge and it appears there directly at night.

Where Rosetower Woods sits in Breezy Plains

Rosetower Woods is a Breezy Plains area with a Lv. 43-50 band, one bonfire, and a dense spread of collectibles, so a trip for Bonesky doubles as an exploration run. Neighbouring zones sit at similar levels if you need to grind before the catch.

Area	Level range	Chests	Lumin amber
Rosetower Woods	43-50	92	13
Zephyrus Landbridge	47-57	58	6
Driftwise Meadow	50-55	40	3
Sea of Flowers	19-28	66	5

Rosetower Woods also has six pathfinder challenges and 43 ecological points, so clearing them on the same night trip saves a second visit.

Building Nighttime Bonesky after the catch

If you plan to keep this form rather than evolve it immediately, put Potential development into ATK, since that is the stat carrying its damage. The recommended personality is ENTJ, where the N letter’s +5% crit rate stacks directly with Biting Wind. Heartseeker Pendant is the held item that fits that crit-focused direction.

Durability and energy regen are both low here, so it does not sustain back-to-back skill casts. Pair it with a healer or shielder, and with allies that strip ice resistance, such as Geoclaw or Stellarys, to make its ice damage land harder.

Resonance Training unlocks at higher levels — LV 6 at level 55 for one Omnisource Crystal, and LV 7 at level 65 for two. Outside combat, its Hustle mobility skill makes it a reasonable field traversal pick, which is useful given how much of Rosetower Woods you will be crossing on foot.
