Dune Awakening has you pick from 5 classes as you begin your game, but thankfully, the game gives you the option to try and train for other classes as well as you progress through the game. This is done by locating 2 ‘Trainers’ for each of the classes at specific locations: a Basic and an Advanced One.
Basic Trainers unlock Tier 1 skills, Advanced Trainers unlock higher-level level, and Capstone skills for each class.
So, if you have selected a starting class but have set your eyes now on something else, here are the trainer locations for all classes in Dune Awakening.
All Trooper Trainer Locations

Basic Trainer: Head to Haga Basin South to come across a trading post. You will find Ghavouri in the market area.
Advanced Trainer: Travel to Arakeen, and you will eventually come across Kara Valk in one of the buildings on the second floor.
All Mentat Trainer Locations

Basic Trainer: Head to the Rift Watch area, east of Haga Basin. There will be an outpost here where you can meet and train from Samin Morro
Advanced Trainer: Zayn de Witte is the advanced trainer for Mentat and is located in Arakeen, at the very end of the bar.
All Bene Gesserit Trainer Locations

Basic Trainer: Go to the southernmost edge of the Shield Wall near Jabal Eifrit. Here, you will find Sister Mesa
Advanced Trainer: Go to the second floor on one of the pathways in Harko Village to find Jocasta Cleo
All Swordmaster Trainer Locations

Basic Trainer: Head to the northern edge of the Shield Wall near Jabal Eifrit; and you will come across Arno
Advanced Trainer: Again, like for Bene Gesserit, head to the Harko village to find Seron Varlin in one of the lesser crowded areas.
Planetologist Trainer Location
Basic Trainer: Head to Griffin’s Reach Tradepost to find Derek Chinara, the Basic and only Trainer for Planetologist.
