As a soothsayer I coved the entire ground with ice spikes the spider adds couldnt fall /profit

I did this as Soothsayer without trolls using Jarls, Warrior Maidens, Royal Snakes, Polar Bears and Swap Snakes. I found I can buy trolls at the map AFTER I killed the spider (the dwelling is not shown on map). The idea is try not to melee spider much with any other units than Jarls and Bears. Snakes and maidens should clear spiders, while using ranged/bite attack on boss when its ready. Use protection spells on jarls and bears and offensive on the boss. You will kill him eventually, but if you aim for some achievements or dont want to lose many units (as you will), use the trolls and profit.

That was something I had in mind... so it's possible... I'll try it.
That's the point - it's easy to kill him, but I want to kill without any losses. I have 3 trolls but they don't seem to deal a lot of damage :(

The spiders fall from sky but die instantly lol too funny

Yeah well..I was talking about impossible difficulty :D

I have only first level of rune magic, so my Ice spikes magic gives only three spikes and it's impossible to fill the whole battlefield. And I can't think of anything else :( Is there no other way to kill the spider without losses? Doesn't nobody managed to kill it without losses with different tactic that filling the battlefield with spikes? I've beaten all the previous games without losses on impossible, and now I can't even kill the first boss on Normal. WTF?
edit : just killed it. Used only trolls split into three groups of one. Easy but long battle - around 50 rounds. Didn't like it, seems the tactic with the trolls is the only designed way to defeat the boss without losses.

Finally beat it last night on impossible my icespike trick took while and lots of luck. Needed him to not drop spiders down a few times to catch up on the ice spikes. Trolls are so awesome with their instant life return on start of next round.

I needed a quite a few tries.
Initially I used assassins and maidens, but i kept reloading because i didn't want to lose any of those.
Then I used Trolls (3), Jarls, Polar Bears, Royal Snakes and vikings.
I used the trolls, snakes and bears to attack the spider (boss). Jarl allowed me to attack twice the spider with bears. Then in the middle of the battle I also used vikings to attack her (all of my vikings died)

I defeated the spider in 11 rounds(achievement) on impossible.

This is what i used: (Warrior - Impossible)
I had to restart a few times because he kept using range attacks in almost every rounds and both maidens had resurrect in cool down.
But in the last battle he got busy with the ancient bears from call of nature spell
Just before the final blow , the snakes made a critical hit of 11 000 dmg on him.
I didn't got the achievement but at least was a no loss battle.

11000? :shock: HOW?
