Chora Nectar is a core Sky Logistics material, shaped around containment, storage, and expandable space. It is not only used for expansion; it also appears in base recipes for sky containers, nodes, and upgrades. It is made through sky offering.
The Chora Nectar recipe requires a tier 2 altar. Place a charged Eulogia Crystal on the altar, then place 4 Dragon's Breath, 4 Diamonds, 4 Amethyst Shards, and 1 Glass Bottle on the four offering tables in any order.
The ritual takes about 12 seconds by default. When it completes, the offerings and crystal are consumed and Chora Nectar appears on the altar. If the altar slot cannot hold it, the item drops above the altar.
Nine Chora Nectar pack into one Chora Nectar Block, which unpacks back into nine nectar. Four blocks replace the corners of the inner 5x5 frame to upgrade a tier 2 altar to tier 3. The block remains mineable but resists explosions, lava, Withers, and the Ender Dragon; sneak-use a compatible wrench to recover it instantly.
