Trench Decay: Classes and Progression

Medic covers recovery, Engineer covers fortifications, and Quartermaster covers supplies. Read the role that matches the actions you want to perform during your next sessions.

Make a specialization worth the Medals

Normal classes commonly cost 150 Medals after Level 5, while special classes have different access. The directory explains that distinction. The individual support articles develop positioning and priorities rather than repeating the same unlock table. Pick a role you want to progress, then use its associated actions during a mission.

Class-specific actions earn skill points. Medic progresses through healing or reviving, Engineer through building, and Quartermaster through collecting items. A specialization is easier to justify when those are actions you want to repeat, instead of buying several roles before deciding how you want to help.
