Farming Souls in Far Far West is essential for players looking to enhance their builds through Joker cards. The most effective method to accumulate Souls is by defeating enemies during runs, as each kill contributes to the total. Players should prioritize clearing enemies rather than rushing through maps to maximize their Souls per run. Additionally, graves scattered throughout the game serve as valuable sources of Souls, and players should make it a habit to collect from these locations while navigating the maps. Completing map challenges is another lucrative strategy, offering 1,000 Souls for each challenge, with a potential total of 7,000 Souls from all map challenges. To further optimize farming, players can equip the Soul Reaper Joker card, which provides a 20% bonus to Souls earned at the end of each mission, and the Soul Siphon Joker card, which increases soul pick-up range by 200% and restores health with each soul collected. Combining these strategies makes farming Souls more efficient and less of a grind.
