using bury
Bury does not leave corpses on the terrain, therefore it stops the enemy from using raise dead on dead troops. This is particularly useful in areas guarded by a totem of resurrection.It also stops carrion creatures like lord and chief wolves, and all trolls, from feeding on dead bodies, and regaining health.
Any creature can be resurrected, but undead lawful troops are hard to bury, while undead chaos troops are easy to bury.
