I know you're not supposed to repeat the same action in a turn,
What do you mean by repeat the same action in a turn?
Each action can only be done once per turn. The example given in the rulebook is that you can't negotiate with 2 Friendly tribes using 2 Negotiate die rolls. You can negotiate with 1 Friendly tribe using 1 die and 1 Wary tribe using 2 more die, as that is 2 different actions.
