RPG 2 – The demons are coming!!!

The next morning, all the wounded were almost recovered...
I went into the druid's hut... there was an elf... It was immediately clear that he was in very bad shape... And the druid promised that everything would be alright :( How could this be? - I asked him with a silent question in my eyes.

Then, the Druid came out of the hut and said:
- The situation is bad... His body has been subjected to a strong influence of death magic... Moreover, the one who cast the spell was obviously very powerful. Only Silana knows why he is still alive and holding on so well, but the bony old woman is taking her toll... he is slowly dying.
He can be saved by the life-giving power of the Forest. I must perform a cleansing ritual, but for this, I need many different components, and unfortunately, I don't have them all with me...
In 4 days, there will be a full moon. By that time, I need to collect a handful of sleepy berries, about 6 leaves of moon flax, sparkling water from the spring, singing wormwood, and a couple of suo algae. I have everything else.
- I will send rangers to search. If you want, you can help. You won't be able to collect all of this yourself, but you can help the rangers. As I understand it, you are close to the water... If you agree, go to the sparkling spring, I will show you where it is, and collect some of its water. At the bottom of the lake, you can find suo algae and possibly even moon flax, although this is a very strange plant... The rest is far from the lake, and the rangers will take care of it. So, do you agree to help?
