Golems

If want us to break through this wall, we're gonna need twenty sappers, seven mules and a hundredweight of saltpeter. Or one golem.

Golems are mindless matter brought to life by a spell. They obey their creator's orders without question. Their boundless strength, ability to withstand pain, endless patience and the fact that they need not one jot of food or drink makes them the best servants or guards anyone could ask for. Once provoked, they will not tire of battle until they have either crushed their opponent or themselves crumbled into dust.

Defeating a golem is extraordinarily difficult: for obvious reasons it does not bleed, if feels no fear or mercy and it is invulnerable to fire and poison. What's more, a golem's body is as hard as the rock it is sometimes heft out of, so even a silver blade will barely wound it. The monster's only weakness is acid – a blade covered in acrid oil can thus increase one's chances for victory.

Golems use no weapons, for they have no need – their fists, weighing over a hundred pounds each, can crush solid granite with one hit. A blow from a golem should thus be avoided at all costs – there is no shield that can stop it, nor sword that can parry it. That is no easy task, for these creatures are able to move with surprising speed. Luckily, their enormous mass means they are not very agile – once a golem begins a charge, it cannot stop quickly, a fact experienced witchers use to their advantage.
