Baleful Nova (禍星) — Sealed Star Spell [VRChat / Modular Avatar]

The sealed star is cut down.

A spell gimmick for VRChat avatars. Cast it from the Action Menu and it plays out over about 58 seconds.

Sequence

1. A magic circle assembles in front of your right hand (or at your feet).
2. Particles of light streak from behind you and converge at a single point in the sky ahead, forming a sphere of lines.
3. Sealing rings close and begin to orbit the sphere.
4. The sphere swells. A red core surfaces inside it.
5. It is compressed at a steady pace until the core turns into a pale blue star.
6. A diagonal cut of sealing red splits it, and it explodes.
7. Shockwaves run vertically, horizontally and across the ground.
8. The fireball rises at full size, drawing sand up from the ground into a mushroom cloud.
9. After the fire is gone, a cloud of black smoke remains, with lightning running through it.

Scale

The core forms about 70 m in front of you and 34 m up. The spell stays where you cast it, so you can move freely afterward.

The sealing rings are about 64 m across, the fireball is about 120 m across (rising to about 180 m), and the shockwave spreads to about 400 m. Use it in a wide world.

Menu

Action Menu → 「禍星」 (Baleful Nova)

- 「撃つ」 (Cast) — default off. Turn it on to cast (~58 s), then turn it back off when it ends. Turning it off midway removes it on the spot.

- 「画面効果」 (Screen effects) — default on. Screen shake and distortion when the shockwave reaches you.

- 「足元に出す」 (Cast at feet) — default off. When on, the magic circle appears large at your feet instead of in front of your right hand. Switch it before casting.

Install

1. Import the unitypackage into your Unity project.
2. Drag Assets/RuptureCore/RuptureCore.prefab onto your avatar in the Hierarchy.
