Phantom spire
by Paycys
Phantom Spire adds a structure of two levels that lets players walk through the air, built from Phantom Pillars and a Phantom Spire block at its top center.
What it does
The structure is raised from vanilla copper blocks used as its foundation. Copper blocks behave the same everywhere and their oxidation and waxing have no effect on the build. Its capstones and column are made from froglights, and the two levels differ noticeably in range.
To build a spire, a player first crafts Phantom Pillars, which need Create, and then places a Phantom Spire block on the top central pillar. Unlike copper blocks, the froglights in the structure must all be of the same type for the spire to operate. Geckolib is required, and the mod is server-side only, so players join without installing it.
Froglight choice sets the mode: a Pearlescent froglight gives a simple mode, a Verdant froglight a building mode, and an Ochre froglight a bridge mode. The mod is published for Forge and NeoForge, with files for 1.20.1 and 1.21.1, and the code is all rights reserved, not open source.

Use cases
Who it’s for: Players who enjoy building vertical structures and server owners who want a walkable air route on a server, since only the server needs the mod.
How it compares
Craftable Froglights works on Fabric, Forge, NeoForge and Quilt from 1.20 onward, and needs the server while clients may join without it. Create: Froglights is server-side only, runs on NeoForge for 1.21.1 alone and is licensed as All rights reserved. Both are alternatives in the froglight space, while Phantom Spire is limited to Forge and NeoForge.
