Traps (King's Bounty: Dark Side)

Comrades, does anyone know where in the file it is possible to nullify the award of Trapper ? And at the same time, reduce or even eliminate the possibility of traps on the map ? Pulled up already ! 6 units on the map !!! Almost half of the woodpeckers dies on them. From the infantry and the riders had to give up - to foes walk not really. You have to use only the arrow and aviation. Generally, a half interesting units, because of these traps, almost impossible to use. And the remaining half is also really did not show in time. All of the same traps.
