Suspicious Flora

Oh hello traveller! Are you ascending to the summit? You must have been very brave to sneak past the demons. I am sorry, but is it okay if I ask you to help me a bit? Please?

I have felt the plants cry out in distress, something is wrong with them. Can you pick me a few samples in the area for me to look at while I try to speak to the trees?

Grab them delicately from the ground, roots and all. I will return them to their home later!

Well? Did you succeed? Please! It is important.

Thank you! Let's see?Oh no! Some of these plants are fel tainted, but the taint comes from the root!

This is bad, I hope I can count on your help! Here, take these shinies. I will get you more if you help!
