Hit quit recommendations: low difficulty playing a key difficulty playing Ring

First, we note that tells us that a simple calculation the: best brush key difficulty may be in the fact that between 1 to 5, I think it is basically correct.

However, this analysis also less very important step is to brush ring is a secondary process, brush the keys is just the first step, you also need to use the key manufacturing the purgatory machine defeated the boss to get the ring synthetic materials.

Suppose we use the optimization process is the 3-person team, each brush full time key together to fight the boss (brush key team apart is the same, because of the drop of independent and identically distributed).

I assume you in a difficulty, materials drop rate p1 brush 3n times you hit the boss's difficulty falling rate p2.

The n key farm you get the average np1 group purgatory machine, and then hit the boss, the np1 group purgatory machine for np1p2 rings.

Of course, in fact, this is wrong, because you can synthesize purgatory machine number and ring number not expect, and depends on the fall of at least that amount of material, but if you brush enough, the gap is very small in order not to problems and made too complex, simple calculation No. (I later simulated by computer, actually gap and np1p2 this model is also less than 1%).

Assuming that the farm is completely proportional to the monster blood, and playing ring boss big appointments need to play a key 2 times.

Farm exists a waste of time, and this time in mp1 difficulty for effective Daguai 3 times time, and the absolute value of this time is not increased with difficulty.

Conclusion:

From the brush ring time efficiency perspective, you should go brush in difficulty between 3 to 7 keys, but always play at the highest difficulty boss (you can defeat the most difficult), you can even pay a certain price, For example, looking for thugs, looking for a strong faction.

The Ring final time efficiency and level off rate is proportional to the square of casually at a low difficulty inside'll save down the purgatory machine wasted.
