I've two items on DMsGuild.

Shifters Unleashed is a re-take on shifters in 5e using the best of each between the UA versions and RfTLW, adding in some feats, a subclass, and changing the racial features a bit among other things.

Rashemen Revisited is my simple attempt to bring some of the more important bits of rashemen to the current edition.
2 new subclasses, berserker feats, magic items and more.

The artwork in some cases is used with permission and I didn't have permission to edit or change the original art so you'll see some straight lines and such. Just try to forgive me, these are my first attempts.
