Can soul ash be sent to alts? If so how?

[Kaivax]

This is correct.

@Klonus-korialstrasz

There is a vendor in Korthia who exchanges 300 soul ash for 250. Requires renown 44 though. Have to wait till next week.

Hitting Renown 44 and doing some quests will reveal Heirmir in Korthia.

Vendors in Torghast do not sell this exchange item.
