A skillshot VFX sandbox built with **Three.js**, **Vite** and hand-written **GLSL**.

Five abilities and two ways to aim them. Four are **line casts**: press the key to arm, a

Six abilities and two ways to aim them. Four are **line casts**: press the key to arm, a
League-of-Legends style arrow appears on the ground and swings with the mouse, click to fire. Two
are **far casts**: the arrow is replaced by a circle with a deliberately thick boundary that
follows the cursor and answers the only question a ground-targeted AoE has to answer before you
commit — how much space is this going to take.

**V — Voltaic Snare.** The first far cast. A leash of current is whipped out across the floor, and where
it lands the ring snaps open past its own radius and pulls back onto it: a violet column tears up
out of the middle, tendrils crawl outward to the boundary, arcs run around the rim and the whole
disc burns. It holds there re-striking and hauling the air up into the pillar, then collapses to a
thread. The circle you measured out before the click is exactly the circle you get.

**X — Glacial Crown.** The second far cast, and the one that comes out of the floor. A cold front
races along the floor to the aimed point, the disc freezes outward to the boundary the indicator
drew, and a wall of crystal tears up around it — a ring of blades leaning outward with a skirt of
wreckage at their feet. The middle stays open. It stands, glints, breathes cold off its rim, then
shatters plate by plate and sinks back into the floor.

Everything you can see is generated. There are no textures, no sprite sheets and no meshes on
disk except the character: the crystals are procedural geometry, the bolt is a strip of ribbon
placed entirely by a vertex shader, the meteor is an icosphere cratered and sliced by fracture
