Uh-oh, Jan 20, I guess that the above mentioned several week waiting period is not considered any more. And I have a clan-boot cool-off period of 12 days to go.
Anyway, it is not all clear with the clan missions, levels and bonuses. It is probably meant to be learned by trial and error.
My guess is that there are 6 clan missions anticipated so far: 1. Relics; 2. Forge cornerstone; 3. Place cornerstone; 4. Build clan house; 5. Build storage room; 6. Build bar. Now, one clan has apparently finished the first three and the members have 40 individual clan points.
Let's say that all 6 will bring a total maximum of 200-300 points. If memory serves me right, one needs 100 points for level two, meaning that the maximum clan level any individual character can reach is probably 3. The question is: are the 40(ish) points for the first two missions going to make a difference regarding the clan level (which may increase luck by three), or the extra mushroom is better added to luck directly. On the other hand, according to Help, Luck Bonus would increase luck at least by 2, so the end result is the same as with CL = 3 and the mushroom spent on a clan mission.
The point of this long story is: it may not be all that bad if a digger joins a clan AFTER the first two missions are completed. Participation in the remaining ones may yield enough points to reach the same result with regard to luck. Therefore, if you guys go ahead with the missions, I will still probably apply later with my digger when I can, that is, of course, if you'll have me, but the discussion stands for all diggers and clans.
Or, I may be completely off course.
