I wondered one day, "Is it even worth forging minimum or medium?"
So I made a chart of the average amount of fire crystals used in 4- and 5-star forges in each level, and of the different types: minimum, medium, and maximum(The chart can be found here).
To calculate the averages I used this formula: f = a*(100/c); where f is the forge, a is the amount of fire crystals and c is the chance percentage. (Unfortunately, I could not put into account the chance for level skips that medium and maximum forges can provide.)
From the data, I've gathered that
- The minimum forge is an unreliable wasteful forge, only implemented to drive up the crystal amounts for the other forges; and
- The medium forge is your best bet with the least average fire crystals, although not much lower than the maximum forge
If the minimum forge was removed, and the crystal costs for the medium and maximum forges were shifted down, it would bring the large crystal requirements down to a more tolerable level.
Your link is broken. I think that you linked to a file on your own computer, not on a public web server.
We've been talking about this since the Forge came out. You can find many threads where I advise people to use Medium chances, because it costs about 420 Radiants on average. And then players respond that you should use Maximum chances, even though it costs 453 Radiants, because the disappointment of failing a forging is not worth the 33 Radiants that you save. And then I respond that the real disappointment is spending 50% more Radiants per forging. And we go on like that for a while. And in the end most players seem to go with the "emotional" strategy (Maximum), not the long-term rational strategy (Medium).
