Anyway, synergy is a bit more difficult than just looking at the skill requirements. When recipes start needing over 80 combined elemental energies, soloing them becomes very difficult since taking the time to manage pressure and clearing impurities to avoid overloads/leaks means time spent not feeding more fewell while the furnace's HP depletes. This gets even more agitating on synths where you have to feed fewell in a specific order to avoid depleting another needed pool for success.
