REWOLF CUBE 3.0 — KUBEJS V4.1 MAGIC + SEEDS

V4.1 keeps the V4 seed rebalance and adds real shared magic progression.

MAGIC DESIGN
- Ars Nouveau, Occultism and Hexerei can each be entered.
- Important infrastructure then starts requiring the other magic branches.
- This prevents a player from completing the useful magic progression by playing only one mod.
- The cross-links are placed after entry items to avoid a circular deadlock.

ACTIVE MAGIC CROSS-LINKS
ARS:
- Source Jar -> includes Occultism Otherworld Ashes.
- Enchanting Apparatus -> Ars + Occultism Spirit Attuned Gem + Hexerei Willow.
- Ritual Brazier -> Ars + Occultism Otherworld Essence + Hexerei Crystal Ball.

OCCULTISM:
- Spirit Attuned Crystal -> Occultism + Ars Source Gem + Hexerei Moon Dust.
- Dictionary remains available as an entry point.

HEXEREI:
- Book of Shadows remains available as an entry point.
- Book of Shadows Altar -> Hexerei + Ars Source Gem + Occultism Otherworld Ashes.

MYSTICAL AGRICULTURE
