Entry III

It was a request from Golden Sand; there was a monstrous shark undead being found in middle of desert. It is said to have a shell on top of it, resisting the necrotic and fire damage but vulnerable to radiant and cold damage. It was said to have ability to dive inside the sand, like swimming in the middle of ocean. When we arrived at desert, it was said to eat corpses according to two days old eaten corpse.
It was also had unexpecting resurrection and expected sandstorm that would erase the presence of it. In advantage of the mark I put upon, we were able to track it to a temple. It was undeniably strong as some party members would get injured. Its only weakness was a soft skin on its stomach, we wouldn't have made it when its shell fully covered.
Once, it was under my feet, thanks to Bajogg's power it appeared and lifted me so I could stab it from above.
 
The undead should be put into the sleep... for good.
