You’ve probably heard it before: is this game player-phase centric or enemy-phase centric? These terms tell which phase the player deals most of the damage on. Player Phase FE games usually have fewer, stronger enemies, while Enemy Phase games have a lot of cannon fodder that can be dispatched with a unit who has enough attack power and defense. A juggernaut. We’ve all seen these guys: Seth, FE7 Marcus, Titania, FE10 Haar, Xander, Ryoma, Jill, Milady, Percival, Robin… You know them.
People usually talk about this property of games in vague qualitative terms, as in “FE7 is more enemy-phase oriented than FE6”, or “Fates is more player-phase centric than Awakening”. But wouldn’t it be cool if we had actual numbers to compare them?
Fear not, my dear fellows! I’ve done some number crunching in a variety of FE games and come up with a most exquisite formula:
Juggernaut Index = (Damage dealt on enemy phase / Total damage dealt) x (401 x #Maps - #Turns) / (4 x #Maps)
So let’s break it down. The left-hand side of the formula is rather simple: add up all the damage you dealt on player phase and on enemy phase on a particular map, and divide the EP damage over the total (PP+EP). This is the ratio of damage dealt on enemy phase. At first I was happy enough with this simple formula, but then it hit me: your army isn’t much of a juggernaut if you’ve baited all the enemies one by one, adding up to a lot of turns spent.
That’s where the right-hand side of the formula comes in. It’s a multiplier that reduces the Juggernaut Index the more turns you take. It’s designed so that you get a maximum 100 index if you kill all the enemies on the map on the first turn (which of course isn’t gonna happen - it’s an idealized scenario).
Admittedly, the 401 and the 4 are arbitrary; it could be 101 and 1, 201 and 2, 301 and 3, 501 and 5, or whatever you want. It depends on how much you want to punish slow play (or reward fast play), and how big you want the numbers to be across the board. Or you can ignore this part of the equation entirely if you don’t care about turns spent and only want to focus on the damage.
Let’s bring up some actual examples that I’ve gathered from a few let’s plays. These are the numbers for the map Clash in Path of Radiance Maniac mode:
Turn 1
Player phase: 82
Enemy phase: 418
Turn 2
Player phase: 208
Enemy phase: 495
Turn 3
Player phase: 148
Enemy phase: 154
Turn 4
Player phase: 58
Enemy phase: 187
Turn 5
Player phase: 154
Enemy phase: 228
Turn 6
Player phase: 196
Enemy phase: 531
Turn 7
Player phase: 153
Enemy phase: 78
Turn 8
Player phase: 103
Enemy phase: 74
Turn 9
Player phase: 28
Total damage dealt: 3295
Damage dealt on player phase: 1130
Damage dealt on enemy phase: 2165
Here, the Juggernaut Index would be:
JI = 2165/3295 x (401-9)/4 = 64.3915…
The percentage of damage dealt on EP is 65.71%, and this was multiplied by the factor accounting for the number of turns (9).
Now these are the numbers of the ninja cave in Conquest Lunatic:
TURN 1
Enemy phase: 63
TURN 2
Player phase: 30
TURN 3
Player phase: 60
Enemy phase: 33
TURN 4
Enemy phase: 26
TURN 5
Player phase: 39
TURN 6
Player phase: 67
Enemy phase: 30
TURN 7
Player phase: 97
Enemy phase: 90
TURN 8
Player phase: 143
Enemy phase: 97
TURN 9
Player phase: 105
Enemy phase: 33
TURN 10
Player phase: 36
Enemy phase: 63
TURN 11
Player phase: 11
TURN 12
Player phase: 33
TURN 13
Player phase: 28
TURN 15
Player phase: 104
TURN 17
Enemy phase: 30
TURN 18
Enemy phase: 32
TURN 19
Player phase: 32
Enemy phase: 68
TURN 20
Player phase: 153
TURN 21
Player phase: 31
Enemy phase: 2
TURN 22
Player phase: 47
Enemy phase: 46
TURN 23
Player phase: 21
TURN 24
Enemy phase: 28
TURN 25
Player phase: 8
TURN 26
Player phase: 34
TURN 27
Player phase: 30
TURN 32
Player phase: 100
TURN 34
Player phase: 33
Total damage dealt: 1883
Damage dealt on player phase: 1242 (66%)
Damage dealt on enemy phase: 641 (34%)
The Juggeranut Index would now be:
JI = 641/1883 x (401-34)/4 = 31.2330…
And in Chapter 19 of Awakening Hard mode:
TURN 1
Player phase: 73
Enemy phase: 546
TURN 2
Player phase: 98
Enemy phase: 718
TURN 3
Player phase: 80
Enemy phase: 424
TURN 4
Player phase: 59
Enemy phase: 251
Total damage dealt: 2249
Damage dealt on player phase: 310 (14%)
Damage dealt on enemy phase: 1939 (86%)
Juggernaut Index = 1939/2249 x (401-4)/4 = 85.5694…
So now you can brag about your math skills when discussing FE games and maps with fellow FE enjoyers. Just drop the Juggernaut Index in a discussion and look like a NASA engineer.
