Engineering
Availability: Live -- The 'craft' interaction is live through workbench recipes, machines, field devices, bridges, braces, and traps.
Design, build, and repair mechanical devices and structures.
Domain Synergy: Engineering
How It Improves: Use it in the world, practice it directly with practice engineering, and seek out trainers once you push past 75.
Milestones:
25 -- Simple repairs and basic construction
50 -- Mechanical traps, bridges, fortifications
75 -- Complex machinery, siege equipment
90 -- Dragon-era mechanisms partially understood
100 -- Lost engineering secrets recovered
Practical Advice: Skills are long-term investments. Keep the tool or context they need on hand, use them in the zones that support them, and check skills often so you can lean into what your character is already getting good at.
