Defeat Enemies using 3 Different Tribe Weapons
Tribe weapons are special unique weapons you obtain after defeating a Tribe. The first one you are given by your chosen tribe that you take over outposts with after you complete two outposts, then the others are obtained when you take over the Fort of other rival tribes. You have to take over at least 2 Forts for story purposes (after this you can choose to automatically unite all tribes which is fine and doesn’t impact any trophies). So you’d always have at least the 1 you get from your Tribe + 2 from Tribes you defeat automatically from the story.
You can equip these in the Gear Menu > Main Hand > Melee / :r1: Ranged.
Note that there are some Melee and some Ranged Tribe Weapons. You can tell which ones are your Tribe Weapons because they say “Tribe” in their name and start with the Tribe’s Name. The ones you got are also listed in the Character Menu > Wung-Fu (they have their own menu points under Close Combat / Ranged Combat).
Also note that if one of your 3 Tribe Weapons is the Netra Tribe Grabbler (Ranged Weapon), it can’t kill enemies with its default attack but you can use its combos to deal the killing blow (combos found under Character > Wung Fu > Ranged Combat > Netra Tribe Grabbler).
