Fighter/2nd/Tunic
Tunic Proficiencies
At 2nd level, your unconventional training grants you proficiency with bombs, and one musical instrument or artisan's tool of your choice.
Tunic Techniques
Tunics are defined by their employment of fantastical combat maneuvers. Although all fighters can employ some techniques, none could hope to match your versatility and skill. At 2nd level, you can learn any two martial techniques of your choice. You can learn two more techniques every three fighter levels hereafter: 5th, 8th, 11th, 14th, and 17th.
From 11th onward, you can instead learn heroic techniques with this feature (but not with other features that can grant techniques, such as your Improvements). At 20th level, you can learn one legendary technique.
Courage
Starting from 3rd level, you have advantage on all saving throws against being charmed or frightened.
