Restrictions
Cannot be Tempered
Can still be Enchanted/socketed/recycled normally
Socket count on the base item is irrelevant (no sockets needed)
Both normal and Ancestral base items produce a corresponding runeword variant
Crafted result is not seasonal-flagged and transfers to Eternal, but the input runes are S15 seasonal drops, so post-season craftability is unconfirmed
