Someone else doing it would be a nifty challenge for someone! :)

Also, there is usually a healing scroll on the right side of the map but you have to dig it up.

Maybe I just got super lucky but in my 2nd playthrough with a Mage, I still got it.

My 1st playthrough as a Viking/Warrior, I got about 4 Calls of Nature, and a lot of healing scrolls but... no way I could learn Order magic so it was a big trickier.

Started a new run and found 2 call of nature in the first stash , so it looks good so for :D

Tell me this, how on earth do you plan on killing the spider boss without losses?

Either 3 individual troll stacks, 2 individual troll stacks, or single troll stack. :)

CP from other thread:

The undead spiders will kill your trolls fast if you don't have some backup, and that backup is gonna get casualty

Without preplanning, yes, otherwise, not necessarily. :)

I was particularly fortunate with my Viking/Warrior build as I had Slippery Cuirass and Twinkling Boots PLUS Shield of Rage.

This was not one of my shining moments in KB history, as the battle took over 100 rounds. I prefer much faster battles by far. :)

If you don't have Shield of Rage, this battle could take much longer.

This is where three separate stacks of troll is better. You keep trolls in the corner where they can only be hit by 2 spider stacks. You keep one 'weak' spider stack adjacent to one troll and the stack that gets "retaliated" against is the "dangerous" one.

You always attack the spider if he is in your corner.

Even when the spiders get up to 400 or so, as long as you 'defend' that round against the spider minions, you should be fine unless you are in melee against the spider boss (ergo, you need to recasting stoneskin and magic spring).

The spider's ranged "magic" attack is weaker, so you can tend to survive. Unfortunately, without Shield of Rage, the 'bad morale' curse might let a troll die that round.

Single 3 troll stack works with shield of rage fairly well, but I think when I did it, shield of rage was bugged (removed too often) and your problem is getting to the spider boss after he moves from one location to another AND getting webbed.

That said, I might go for the "beat spider boss in 10 round" achievement instead next time around. I was worried I would never find trolls again or I would use them immediately afterwards.

Neither ended up being true as I found over 230+ trolls later on and I was relying on horsemen was my meatshield, attacker, AND interceptor.

The AI is rather chaotic with its actions. Those who try to win the tough battles with no losses replay those battles a lots of times. When the enemy hero cast direct damage spell and the killed units are impossible to be resurrected they replay the battle and do something different. Usually this is enough for the AI to do something different too etc etc. If the AI has the 1st move and use direct damage spell ASAP they may replay the battle with another kind of troops instead with higher initiative OR go for another battle instead. If you do something different there is always a chance the AI will react different.
If you think this is rather boring... well, it is boring indeed - but there are people which enjoy it.

No loss Spider for soothsayers is easy if you have Summon Phoenix and Calm Rage scrolls..... :grin:

I don't think I've ever had either of those spells pre-spider boss.
