Ok. I eventually got the game working and have been busy playing it since Friday more or less

.
Archers, yes they suck and they pretty much always get focused. But early their frost arrow helped me a lot as it kept hostile mobs away for 1-2 turns. I guess I could probably have used priests in their spot. When I go for Impossible with no unit losses I most likely will. That extra heal helps a lot in order to keep the losses down.
I’ve had countless games where I’ve only lost 1-2 units. Often as the last unit would hit my royal snakes and kill a couple, then the royal snakes would kill them in their retaliation and voila reload time.
I only ever use 2 spells now. Resurrection rank 2 and Healing rank 3. I cant upgrade Resurrection to rank 3 as I will only to cast it twice then due to my 61 mana.
I just got Lina as well, but I don’t really get an opening to use Orb due to the way I play right now.
Now I use:
Royal Snakes
Cannoners
Inquisitors
Evil Beholders
Alchemists
Reserve: Archmages and Archers.
I don’t really like the Alchemists at this point, but they server their purpose as I’ve run into the Giants. And their Earthquake makes going for 0 losses horrible if you don’t have units with a lot of hitpoints. Especially as I can only use my res (Inquisitor) on a level 4 unit once during any battle.
So to wrap it up, I’ve cleared out the Freedom isles with all quests except 3 named heroes. (Egby, Puppeteer and Bart Bart this game.). And Im running around in Upper and Lower Hadar now killing what can be killed without to many reloads.
I also use my spirits alot as their extra damage help me quite a bit. So I got the rage spirit exp talents in the Might tree, while I went for level 3 order magic + 3/3 healing in the Magic tree.
If people care I can probably upload my savegame. But unless someone asks for it particularly I won’t.
It is really weird playing like this as I play extremely aggressive and defensive at the same time. (lvl 15 and 0 losses so far)
As always, inputs etc are welcome!
