Swallow. If the bite damage inflicts 12 or more damage, then the Hatori swallow the target. The target can attempt to escape with an Evasion/Dexterity saving throw with a -2 penalty. The target should not be larger than 10 feet. A swallowed target automatically suffers half bite damage every round until neutralized.
Tail Slap. Crocodiles of the Sands employ this attack to stun targets before swallowing them. The target must roll a successful Physical/Strength saving throw or be stunned for 1 minute. A stunned target cannot move or take any other action.
COMBAT & TACTICS
The Crocodile of the Sands hunts by waiting under few meters of fine sand and then emerges, taking the target by surprise. When emerging from the sands the crocodile gains a +2 bonus on sneak check.
Whether the target is surprised or not, the crocodile attempts to stun it with its tail slap. If both the surprise and stun fail, then the crocodile continue attacking and atempts to swallow as many preys as possible.
DESCRIPTION
Crocodiles of the Sands are so named because in many aspects it resembles a crocodile. These huge creatures may measure from 3 up to 15 meters and scientists believe they have extremely long lifespans that can span centuries. Their color range from dark brown, dark yellow, or dark red, depending on the characteristics of the environment they inhabit. They employ a massive toothed mouth that can swallow and rip almost anything edible or barely edible.
HABITAT
Their favored habitat, as the name implies, is a desert with a hot and arid climate. They prefer deep and fine sands, which allow them to “swim” as a fish does. Larger and older specimen tend to avoid those regions where the sand is not deep enough for them to move and hunt efficiently.
BIOLOGY
These creatures prey upon anything organic, and when big preys are not present they roam the sands and ingest every organic substance, from small insects to micro plants. They usually are the only predator within dozen of miles and are extremely territorials. They produce compact wastes with a high caloric power that can match mineral coal. Locals have learned to gather and exploit this by-product where standard fossil fuels are out of reach due to technological limitations or they are not available at all.
