The Rainmaker

Starting point is the Riederberg, wellknown to all motor-cyclists. You can get here by bus as well. I think the cache can be combined with nearby cache "Troppberg" (I didn't when hiding the cache because of the bad weather I've created).
The terrain is quite easy, there are forest roads available until very close to the cache. Therefore I have reduced the suggested rating from 3 to 2,5. I think it should be possible to do this with a buggy if it is a sturdy one. The roads may be pretty muddy sometimes, though.
Special equipment: I'd strongly recommend taking along some gardening gloves. And an umbrella could be helpful (depending on how you behave at Stage 3).

Stage 1:The Hunter
Find out the day (only the day) when the hunter died and take it as A.
Then hike to N 48° 14,845 and E 16° 05,224
where you will find Stage 2 and Stage 3. These coordinates apply to Stage 3 (and will form the base for calculating the cache-coordinates), but Stage 2 is only a few meters away from there.

Stage 2: Fire and Sword
Many have been killed here a long time ago. Find out how many and take their number as B.
Take the number of years it took in the first place to build the object as C.

Stage 3: Do not disturb the Water
It is said that if you stir the water with a stick and pray 3 Lord's Prayers it will rain. I did not try that, but I managed to turn fog to rain by simply looking at it. So be careful, the rest of your caching-expedition depends on it.
Take the number of screws you can see below the feet as D.
The frame around the cross is decorated with smaller and larger "dents". Take the number of small dents on the lower right side of the frame as E.

Now you have all the information needed to calculate the cache-coordinates. I have tried to create a mathematically correct algorithm.

xxx = C * E * 10 + C
yyy = A * B * D

Stage 4: The Cache
N4 = 48° 14,845 - 0,xxx
E4 = 16° 05,224 - 0,yyy

I've done my best to hide it thoroughly. You may have to look and probe around for a while (and use the hint). Please hide it as well again.
The cache is a rectangular plastic box (12 x 17 x 3,5 cm) and contains:
Cachelog, Logbook and a pencil (please do not remove)and some trading items.
