The Cause of the Dwarf Attacks

Help the biologist [111121|Jacob] collect 15 samples of [202331|Ice Dwarf Blood].

I am a biologist. However I prefer that people call me an Ice Dwarf researcher.

Before the Ice Dwarves started attacking humans, they were considered cute. They lived in harmony with nature. But in the last year they have suddenly become very aggressive, destroying countless villages in [ZONE_DRAGONFANG HILLS|Dragonfang Hills]!

We know that they did this mostly because we took their natural resources away from them, which of course enraged them. Still, knowing their culture, I can't believe that they would just spontaneously start attacking us like that. I suspect that this has been caused by some kind of physical change.

It will require sacrificing some of them, but it'll be in the pursuit of truth. Please collect 15 samples of [202331|Ice Dwarf Blood] so I can carry out some simple experiments.

Thank you for your help. After better understanding what's going on, we should be able to avoid a lot of conflict between humans and dwarves.

To understand the reason for the Ice Dwarf attacks, please help me by collecting 15 samples of [202331|Ice Dwarf Blood]. Then I can do some simple tests.
