Iron's Spells: Light Pollution

## New Spells ### Singularity Opens a singularity that contracts over six seconds. Its gravity, its light and the rate it lashes lightning outward all accelerate together: everything within 20 blocks is hauled toward the core and crushed for 0.8%–4% of its maximum health every half second, harder the closer it is dragged. The collapse deals 62% of maximum health within 18 blocks, throws everything outward, and leaves three decelerating shockwaves to pass through. Cooldown 480s / Mana 1800 ### Sky Collapse A rift tears open overhead and runs to both horizons, pouring light out of the gap. The dome then comes apart: six enormous shards tumble down (7% each, 6 blocks), and a keystone 36 blocks across lands last on the aimed point (34%, 14 blocks), sealing the rift as it hits. Cooldown 420s / Mana 1700 ### Stellar Convergence Nine stars of different colours light one after another into a constellation — each a separate light, so the ground fills with nine overlapping coloured shadows. After about five seconds lightning links them into a contracting net, then all nine pour into a column running from sky to ground (6% per second), which finally detonates for 42% within 12 blocks. Cooldown 400s / Mana 1650 ### Second Sun Raises a second sun on the bearing you are facing, an enormous disc filling a good part of the sky. It is a real light source, so everything in the world casts a second shadow that swings round as it climbs. It scorches enemies within 26 blocks and goes supernova after about eleven seconds (55%, 26 blocks). Cooldown 600s / Mana 2000 ## Spell Changes * **Starfall**: meteors now cut in at a 30 degree slant and fall faster, with far longer trails scaled to the body's own size; some shed expanding shock rings. The finale is now **one colossal meteor** instead of three mid-sized ones, falling 96 blocks onto the aimed point (30%, 9 blocks) with camera shake on impact. * **Pyre Star** (formerly "Falling Star", renamed to tell it apart from Starfall): no longer plunges and detonates. It is now a gravity star that orbits for its whole life, hauling creatures within 14 blocks toward it and burning them continuously (2.4%–10% of maximum health per second, by proximity) until it burns out after twelve seconds. Orbit slowed. * **Silhouette**: field widened to 32 blocks, and it now inverts the scene's actual brightness — lit surfaces become black silhouettes and shadowed ones glow — rather than only inverting spell lighting. ## Fixes * Fixed the horizontal split and rectangular banding caused by **Silhouette**. The final blend was writing to the main framebuffer while sampling its attached depth texture, which is undefined in OpenGL; depth is now copied to an independent texture first. * Fixed **Starfall** crashing the client on cast: its entity renderer registration was not taking effect. * Fixed the inversion producing out-of-range HDR values on dark saturated pixels. * Fixed the blend pass discarding the bottom row of the screen. * Fixed star geometry having the camera transform applied twice, and additive blend state leaking into later rendering. * Fixed **Second Sun**'s corona surviving into the billboard corners, which gave the sun visible square edges. ## Audio Added charge, sustain and collapse sounds for Singularity, plus a lightning arc sound and post-detonation tinnitus. The tinnitus is sent to each nearby listener individually, so it neither attenuates nor pans. ## Credits The lightning, shockwave refraction and singularity core draw on the approach and some assets (noise texture, core texture, sounds) from [Some of FX](https://github.com/YangMao-Minister/some_of_fx) (MIT, © 2026 Pizuka).
