I attacked one of them big spiders with a weak army.
Needed the gold and was going for a marginal victory with just someof my troops surviving.
I made the normal "stand 2 tiles distance and wait to hammer him while shooting with archers" tactic that the AI cant beat.
To my surprise!
The one unit the AI had went for just one unit... who had a movment of 3.
And kept chancing it.... as i withrow...
so i began moving in circles with it... as i keep shooting it...
So now my new unbalanced tactic is to put somekind of "fast hero" that can move 3 tiles bakc up wiht -4 archers and just do the "dance of death".
As long as it dosent shoot... or has a limited mana. I can basically take down a 600something unit with a rediculously weak army... especially the trolls...
