The value of Doubler

So recently, I have questioned myself, what is the value of doubler? A 3x doubler allows you to kill a creature using 3x the amount of stamina, gain 3x the experience, 3x the gold. If you lost the battle, you lose only 1x the amount of stamina, the xp and gold lost are also not multiplied.

For those using the 'suicidal' style, where one only has attack and damage, no armor and defense, then effectively, you have lowered the death rate by 3x.

For those using crystalline items, the loss in durability is not multiplied, so again, you gain an effectively level 70 unbreakable spell.

On top of that, it is like walking into a room with 3 times the amount of creatures. But what do you gain in having 3 times the amount of creatures? Can it be measured? Well, that answer depends on the average creature you see in a room to begin with. So, if you see 2 creatures in a room on average, you would normall use 3 stamina (1 to walk into the room, 2 to kill each of these 2 creatures) for killing 2 creatures. Now, you use 7 stamina (1 to walk into the room, 6 to kill each of those 2 creatures with 3x doubler) for killing 6 creatures. Your effectiveness went from 2/3 to 6/7. That's a 29% increase (((6/7)/(2/3))-1). Again, all these depends on average number of creatures in each room, as well as the level of the doubler, so below is a short reference table :

Average \ Doubler 2 3 4 5
0.2 71% 125% 167% 200%
0.4 56% 91% 115% 133%
0.6 45% 71% 88% 100%
0.8 38% 59% 71% 80%
1.0 33% 50% 60% 67%
1.2 29% 43% 52% 57%
1.4 26% 38% 45% 50%
1.6 24% 34% 41% 44%
1.8 22% 31% 37% 40%
2.0 20% 29% 33% 36%
2.2 19% 26% 31% 33%
2.4 17% 24% 28% 31%
2.6 16% 23% 26% 29%
2.8 15% 21% 25% 27%
3.0 14% 20% 23% 25%

So as expected, the doubler is more valuable when the average number of creature is less. The gains from higher level doubler is diminishing, as expected.

I used to keep a list of doubler buffers here, but this tool by Fallen Empire is doing a far better job in updating buffer list :
