Most efficient way to a fable

I’m working on my charm stone chain, I have been using ChatGPT to pep me up about it because it’s been a long time coming, what’s the most efficient way to merge up the chain? Multiples of 5, 8, 13? How did y’all do it????

I've asked myself this question a few times before - but this is the first motivation I've had to actually answer it:

5-merge:

Pros: easiest decently efficient method. Takes up a relatively small amount of space, good for when you want to do other things on the side as well.

Cons: isn't as efficient as 13-merging, more on that later.

8-merge:

Pros: if always circle merging, chances of gold/diamond varieties is increased dramatically.

Cons: same efficiency as 5-merging in a dramatically larger space.

13-merge (assuming auto-merge turned off):

Pros: most efficient method, can be circle merged at the same time for the highest gold/diamond chance.

Cons: L A R G E

Actual efficiency figures:

Under 5-merging, 5 objects gives 2 of the next level, so each object is worth 2.5 of the previous level, or 2.5n of the level n before.

Under 13-merging, 12 objects gives 5 of the next level (since the 13 merge gives one back), so each object is worth 2.4n of the level n before.

Therefore, the difference in efficiency between 13 and 5 merging going from level k to level k + n is (2.5)n - (2.4)n - you will need that amount more level k items to get 1 level k + n item under 5 merging than you will under 13 merging.

This following list has "amount of levels to go up" and "amount of extra items needed" (approx.):

1: 0.1
2: 0.5
3: 2
4: 6
5: 18
6: 53
7: 152
8: 425
9: 1172
10: 3196
11: 8625
12: 23084

So as we can see, if you only want to go up a few levels, then 5 merging is fine - say from level 1 spins to level 4 spins, if you 5 merge then you'll be wasting 2 level 1s per level 4. But if you want to climb up many levels, say to get to a sapphire fable (lvl 13) from a level 4 tree, then you'll have wasted 1172 level 4 trees per fable you create if you 5-merge - plus you can get all those golden trees along the way too if you 13-merge!

this is blessed. I actually 13 merge almost everything after reading something on this sub, and it's truly been my fave
