Starlight Altars & Crafting

Advanced crafting is powered by starlight gathered from the night sky at altars.

Luminous Crafting Table - the first tier. Place it outdoors under the open sky; it slowly collects ambient starlight and lets you craft the mod's early advanced items.
Starlight Altar tiers - upgrade the table into progressively larger multi-block altars (Starlight Crafting Altar and beyond). Higher tiers hold more starlight, craft more powerful recipes, and benefit from nearby Collector Crystals feeding them extra starlight.
Starlight charge - altars display a starlight bar and project light beams and effects while working. If an altar runs low, crafting slows or pauses until more starlight is available - so placement matters: build under open sky, at higher altitudes, and away from light pollution for the best starlight.

Feeding altars from a network of Collector Crystals (below) is the usual way to keep high-tier recipes supplied.

Astral Sorcery can push your gear beyond the normal enchantment limits.

Dynamic enchantments - certain perks and attuned amulets grant additional enchantment levels to your equipped gear on top of the normal cap, so a well-built character effectively wears stronger enchantments than vanilla allows.
Attuning tools and armor - tools and armor can be attuned to a constellation to gain constellation-specific bonuses, tying your equipment into the same star system as the rest of your progression.

These systems reward investing in constellations and perks by making your existing gear noticeably stronger.

The mod adds a large family of decorative marble blocks used both structurally and cosmetically.

Marble variants - plain, carved, engraved, pillar, brick, chiseled, and runed marble, among others, for building temples, observatories, and altars that fit the mod's celestial theme.
Structural role - many of the mod's multi-block structures (altars, the Attunement Altar, ritual setups) are built largely from marble, so you will gather and craft a lot of it.
Aesthetics - the marble set makes it easy to build grand, temple-like bases that match the starlight machinery on top of them.
