For effective stat building you'll want to watch the timing of specific actions, especially during combat training. When practicing with Bernard, dodge precisely when his weapon flashes (about 0.5s before impact) which builds Agility faster than standard blocks while staying about 2 meters away gives you the best reaction window. For Strength focus on using two-handed weapons particularly maces since they have a 1.2x multiplier on strength gains during successful hits and maintain overencumbered status while traveling between settlements, just keep at least 40% stamina to avoid exhaustion penalties

The most efficient Vitality method involves continuous sprinting between objectives while mixing in jumps every 8-10 steps, and chain-dodging during combat (3-4 dodges before counterattacking). Try positioning yourself near stairs or slopes during practice sessions since uphill movement provides a 15% boost to Vitality gains compared to flat terrain

A quick combat sequence that builds all three: start overencumbered, sprint 20 meters toward Bernard, chain three dodges as he attacks, counter with a heavy weapon combo, then retreat uphill while maintaining gear weight above threshold. Repeat this pattern focusing on precise dodge timing and positioning relative to elevation changes for maximum stat gain efficiency

Remember that fatigue penalties kick in below 30% stamina reducing gain rates by half so time your training sessions around sleep and meal schedules
