here what i got from Seb and Henrik after it was discussed multiple times on discord.
nothing material or anything that would give some sort of Head start in any form will transfer over. so no equipment and spell-books.
the equivalent wealth will come as something, a special item or something. we don't know. but the itself is said by Henrik that it wont give a head start <Henrik's word>
the equivalant wealth transfer is mostly for capes, vet points. henrik said that wealth can also be different than equipment and money and that the biggest wealth we have is the knowledge of the map. "the biggest value we have VS new players" is our knowledge of what animal, stones gives what and were to find it.
TL: DR nothing transfers over except vet points and cape and something "special" henrik will give us. so nothing that gives u a head start over new players.
