Warlock – “Clan Leader” [Campaign 4, Mission 1]

I understand that you doubt whether it's possible to eliminate five heroes on the first day of the tournament. Level up Logistics! :)\

I checked the save file. Railag was 13-3-12-2 with advanced logistics, higher education, expert defense + resilience, advanced luck, and advanced chaos magic. His artifacts were: a +2 sword, an ice shield, a clover, and boots of travel.
