Yeah, I haven't got the second Treasure Chest upgrade yet - it keeps offering me other stuff which is kinda frustrating. I think I will take your advice and rush for the amulet in Bolo - I need those Paladins soon and I doubt I can clear out Bolo and Scarlet Wind without them.
Current team - Inquisitors, Royal Griffins (4 in Scarlet Wind only), Royal Thorns (3 of 4 available on Debir), Archmages (only 4 available - leadership allows 7) and Ancient Vampires (7 or 8 on Scarlet Wind). This is a nice team for no losses and I am up to 31 fights without loss (meaning I got the second Grand Strategy medal - 1500 leadership on level 6). I was able to clear about two thirds of Scarlet Wind but there are still 5 or 6 tough stacks left and I doubt I can take them at the moment.
The key to zero losses at the moment is having units with high hp (at least the highest currently available) and even more importantly units that can summon/spawn units. Thus Royal Thorns and Royal Griffins are a must. Inquisitors provide the rage and the occasional resurrection, Archmages provide Magic Shield and Ancient Vampires are just awesome in every way.
So it's off to Bolo next. Well, in the morning.
