Sky Offering Circle
Place the altar at the center with one offering table on each horizontal side. The Celestial Stone outer ring sits one block below the altar and forms a 5x5 lower frame; other empty-looking spaces do not need to be air. Chora Nectar requires tier 2.
Tier 1
Tier 1 requires the lower outer frame to remain complete. Celestial Stone, slabs, stairs, and walls all count as frame blocks.
Tier 2
Tier 2 adds one Celestial Stone pillar at each corner of the next outer ring, with Celestial Glass on top.
Tier 3
Tier 3 keeps the tier 2 outer pillars and glass caps, but replaces the four corners of the inner 5x5 frame with Chora Nectar Blocks. It processes offerings at the configured base multiplier, which defaults to 4x.
Celestial Glass is made through a tier 1 offering: place a charged Eulogia Crystal on the altar, then place 8 of any glass and 8 Glowstone Dust on two offering tables. After about 8 seconds, the ritual produces 8 Celestial Glass.
