How do you beat Super Boss fights with no losses?

Level 40 seems quite a long time to wait, especially on medium. While he could certainly wait a bit, I think his biggest problem is a lack of damage. Shaman, Archmages, and Inquisitors have nice utility but crap damage. Green dragons are tough but crap damage. Paladins have utility and are fairly tough but below average damage.

What units you choose depend a lot on what skills/spells/items are available to you and how you want to play so it's hard to make specific recommendations. But a no brainer in my opinion would be to swap the shamans out for a damage dealer. Royal snakes perhaps, good damage and no retaliation, not terribly fragile (very tough vs. poison). Lake or forest fairies maybe, excellent damage (absurdly so with assasin's dagger), no retaliation, fast flyers, very fragile however.

Try swapping the dragons with royal griffins. Phantom them and have the stacks of angelic guards attack the boss while the original griffins help clear the summoned spiders.

Hell, if you go with lake fairies, forest fairies, and royal snakes, you might be able to hurt the boss so quickly he doesn't have time to summon spiders. I don't recall how much leadership you need for that though.

Well, I guess that (Royal Snakes, 2xFairies, Dryads and Paladins for emergency ress) may be possible on normal. The biggest problem is that if they can't kill the boss straight away, he's in for some trouble, because the boss has a very high chance to hit with both his feet if there are available targets, and that would devastate any Fairies, Dryads and Snakes, because his damage is physical-based in that case and is well over 2k... Lostkiwi wants a no-loss, which may be a problem is such case, because if you're left with some mediocre spider stacks, there is the danger of killing them before you ress properly.
