You can select the Totem path when in the starting room and you are selecting things like height, awards, gifts, and so on. OR you can select a Totem path by speaking with one of two FOIG NPCs who will offer you different Totem options, once you have 4 or more Ranger levels, as the trigger for the conversation with the NPCs is based on Spellcasting access, which Rangers get at level 4. The two NPCs have different Totem options, based on their thematic location, so if one does not offer what you want, you will need to seek out the other NPC.
It's not something you can just select by typing -path.
