Ok, but in any case there’s no connection between armor and Warrior Rune. People with better equipment do not benefit more from the Warrior Rune.
I don’t understand what you mean by order of runes equipped.
The characters I use for demonstration are all between Lv37 and Lv40, and they all have at least 2 rune slots. Kyril, Mizuki and Lazlo however have a fixed rune, so they have only 1 open rune slot yet. Luckily their fixed runes are useful.
Calculations for all configurations are a good idea, but it’s too much work, it would be hundreds of combinations for each fighter. Let me suggest the following: I will present the formulae for every character, but only at 1 particular level (e.g. Frederica Lv39), and the formulae will take into account the stats at that level, how many rune slots, and how many spells. If someone has 2 open rune slots, I will only present formulae of combinations of 2 runes. I will also take into account how many spells of which level someone has, because this decides what a character will do throughout the 5 or 6 turns.
You can then change the formulae at will. Like if you have a Lv30 Frederica, just replace the stats accordingly and change the formulae accordingly. Or if you want to apply damage multipliers that I ignored, just apply them. So let me explain you how to do that:
((Atk + PDf/2 - enemyDef) x ratio_mod x direction_mod x terrain_mod x battle_lust_mod x command_rune_multiplier) + Mag + MDf/2
This is the damage formula for 1 attack. For an understanding of the terms, see viewtopic.php?f=40&t=9537
+ PDf/2: only if Warrior Rune attached
x command_rune_multiplier: only if command rune spell is used, only relevant if multiplier ><1
+ Mag: only if Magic Sword used/activated
+ MDf/2: only if Magic Sword used/activated and Wizard Rune attached
Modification example: My Lv39 Frederica attacks a Def 40 enemy, she's on her terrain with Battle Lust S, Magic Sword activated and Wizard Rune
((135-40) x 1.3 x 1.35 x 1.8 ) + 40 + 18.5 = 359
Modification example 2: My Lv39 Frederica attacks a Def 40 enemy with Battle Lust S, Warrior Rune and Strong Arm
(135+17-40) x 1.3 x 1.8 x 1.5 = 393
Note that I will calculate 5 or 6 turns rather than just 1 (to take the gale rune into account), so some formulae will become more complicated when you do different actions throughout your 5 or 6 turns.
