Journey: Discipline of the Mentat

How skill points work

Every skill shows the game's point cost for each of its levels. Attributes start cheapest, abilities and techniques cost more, and spice skills cost the most. A skill also needs one of the skills it links to in the tree. Levels 2 and 3 and the capstone at the bottom of each block stay locked until the advanced trainer's contracts open them.

If you want to learn the craft of the assassin, you will need to start with the basics. We will begin with poisons. Bring me some plant fibers and iron ore. I’ll combine these with some of my own materials to create a lethal toxin. Once that is done, you will practice administering it. There are Kirab camps near Mirzabah that will serve that purpose. No one is going to miss those bandits.
