DQ’06

Four minor skills:
Swimming - AG+EN+ST+(10*Rk) - (Distance in Ft/100) = Success Chance
Climbing   - AG+MD+ST+(10*Rk) - (Distance in Ft/2) = Success Chance
Hunting    - (10*Rk)+(5*Ranger Rk, if in specialty) +/- Terrain Abundance (+20 to -20) =SC
Fishing     - (10*Rk)+(5*Navigator Rk, or years at sea) +/- Water Abundance (+20 to -20) =SC

Costs are the same as Horsemanship.

This may give you bonecrushers a few more 4's & 8's.
