When do shamans learn how to use mail

I think there may be some confusion here!

Shamans are spiritual practitioners who work with the spiritual realm, often using rituals, meditation, and other practices to connect with the spirit world. They typically don't use physical armor like mail (also known as chainmail) as part of their spiritual practices.

Mail, on the other hand, is a type of armor that was historically used by warriors and knights in medieval times to protect themselves from physical harm. It's not a tool or technique that shamans would typically use or learn.

So, to answer your question, shamans don't learn how to use mail because it's not a part of their spiritual practices or traditions.
