Impossible Warrior challenge

[Calinda]

Why, no loses with warrior is pretty possible, just drag inquisitors with yourself all the time. As you said, besides the resurrection, they generate rage with the holy anger. Rage can be turned into mana via the chargers skill of Lina. Until you get Lina you can recharge your mana by using Magic Spring and eventually Target, depends on situation. Target spell is one of the most important ones for warrior. It has short duration but you can extend it by cating it after the target unit has moved if the situation allows it, and waiting it when the last turn of it is about to expire.
Besides inquisitors I like to drag archmages with me all the time, mainly for their shield spell which is very important for your tank in the hard battles. Lvl 3 stoneskin + shield from mages and your tank wil barely suffer any physical damage at all.
When you are tanking ranged units consider leaving your tank in the back line so the enemy suffer from range penalty.

Sword of Darkness if I remember correctly gives the +5 attack (+10 in nighttime) but I *think* gives the -20% defense to humans/elves. Not certain though as I don't really remember for sure.

I haven't really used Target before but I will learn for this game. I suppose the Inquisitors can resurrect too, but it doesn't seem like they can do so in large enough numbers early in the game. Basically, I haven't learned the knack of 'no losses.' I seldom lose very much at all, but I will often lose a couple of Swordsmen or a Royal Snake here and there.

Just sneak around and steal a couple of banners early on and you can wipe most of the stacks without any loses. I usually go for archers/archmages/priests/inquisitors + horsemen (sneak into the knight's tent). Horsemen tank very well, you can do it with swordsmen/guards instead but it is harder so why bother.

And about Target - there is more in it than what meets the eye, as it also prevents the use of special abilities if you play it properly. I.e. if an unit is in the Target's range for its normal attack, it will use it and won't use the special abilities. Also be careful when you block the basic attack of some ranged units, cause they can turn to specials then.
