Seeing as Fossils and Archeology is updating to 1.12, I figured it could add some things to Totemic. You could have Buffalo and Eagle DNA, as well as totems for some of the Ice Age mobs (the Sabertooth, Mammoth, Irish Elk, etc.).

Will probably not happen for the 1.12 version of Totemic.

Probably not going to happen, but no one has done an addon for this mod.

Maybe the woods could be supported for poles.

I guess it is on you if you want to add something since you know the mod better than me.

Custom wood support isn't a thing yet (#62), but probably will be in the 1.13 version.
