Minstrel leveling guide outline provided with a detailed plan. Currently there is no reason to play a blue minstrel while leveling with it’s focus purely on healing. A grouped leveling build might be worth it after level 75 when you can start adding in red traits while mainly blue.
For leveling you’ll want to go red and pick up damage focussed trait in yellow.
