Sand Traps

Description
Only a hungry mouth and tentacles can be seen of this creature in the sand, but it is already enough to be a warning not to come any nearer. The sand trap is a horrible foe, strong in offensive and defensive. Their biggest weakness is their immobility, but they often make up for this by placing themselves at narrow passages. However, should a Sand Trap be slain, big treasures await the hero.

Sand Traps only exist in dungeons and the desert.
