The problem is now with legiondraconis, whether he has any save files before entering hall of echoes. With tons of potions, the battle shouldnt be able to finish even not well geared or skilled.
THAT's THE reason I begging Larian they make next time a game
without such a supide thing: CAN'T go back out the Hall of Echoes to Orobas Fjords!!!
Most stupide and frustrating affair!!!!
