No story spoilers or choose options, purely for mechanic obsessive people, how you are able to increase each stat. Some of options have fail chance, and some do only one gain per map ( "oncePerMapVisit" - so retreat and come back should help? - good luck traveling out and back for every mine in minefield :D ) Sources are lua files from game Data.hpk:Data.hpk > SectorOperation.lua Data.hpk > StatGainingPrerequisite.lua And for merc stat mechanics (storage, AP):Lua.hpk > Lua/ClassDefs/ClassDef-Zulu.generated.luaLua.hpk > Lua/Mercenary.lua Merc (even IMP) is starting with random XP at start between 0-600 for IMP, for AIM merc it depends on their level. When and how exactly point is added, ... I tried to follow from Stat increases("SetPrerequisiteState") to "RollForStatGaining" where "roll = InteractionRand(100, "StatGaining")" and I found several Cooldowns - some related to campaign time so related to last skill increase and some related to Map ... Adding Stat Point You only gain 5 statGainingPoints per level, when you advanced 20% toward the next level, 40%, 60%, 80% then when you reach a new level. Level-10 mercs can still gain statGainingPoints ... 引用自 MouToN：source: function RollForStatGaining(unit, stat, failChance) in Lua.hpk > Lua/Mercenary.lua Each time you get a stat increase by field experience, you get a random cooldown between 1 and 2.5 days (only for this specific stat). The triggers described in this guide are called "StatGainingPrerequisite". In order to gain an actual point in a stat, you first need to store "statGainingPoints" through XP (I have not analyzed this yet, but i suspect that this is where wisdom is valuable). These "statGainingPoints" are shared between all stats and are consumed by successful stat gain (-1 for any stat increase through "field experience"). If your merc's pool of "statGainingPoints" is at least 1, if the cooldown is over, and if your merc's current stat is between 1 and 99, then for each "StatGainingPrerequisite" met, you roll a first dice between 1 and 100 for the fail chance of the prerequisite (if not mentioned in the guide, this is guaranteed). Then you roll another dice between 1 and 100. If this second roll is greater or equal to [merc's current stat - 30] (ie. 100% chance for a 1..31 stat, 99% for a 32 stat, etc., until 32% for a 99 stat), this stat will get increased, a new random cooldown will be set, and a point will be deduced from this merc's "statGainingPoints". You only gain 5 statGainingPoints per level, when you advanced 20% toward the next level, 40%, 60%, 80% then when you reach a new level. Level-10 mercs can still gain statGainingPoints when they get 2000 XP past the level-10 milestone, then when they get 4100 XP (2000+2100) past level-10, then 6300 XP (4100 + 2200), then 8600 XP (6300+2300) so basically they get their n-th points after 2000*n + 100*n*(n-1)/2 XP.
