Luck system for rolling system

[static snow]

math.random returns a random normalized value

is that what you need?

wait thats not the question

you'll have to calculate the chances based off base chances and chance multipliers

im not too sure how you're calculating the chances but you can store the player's rarity multipliers somewhere and just reconfigure the chances when rolling

local AuraChances = require(game.ReplicatedStorage.Modules.AuraChances)

local function deepCopy(original) -- function from roblox docs
    local copy = {}
    for k, v in pairs(original) do
        if type(v) == "table" then
            v = deepCopy(v)
        end
        copy[k] = v
    end
    return copy
end

local DeltaChances = deepCopy(AuraChances)

local RarityMultipliers = { -- example table
  {Name = "Unique", Multiplier = -20}; 
  {Name = "Devil", Multiplier = -70}; 
}

for _, chanceTbl in RarityMultipliers do
  if not DeltaChances[chanceTbl.Name] then warn(chanceTbl.Name.." is not a valid rarity") continue end
  DeltaChances[chanceTbl.Name].Chance += chanceTbl.Multiplier
end

@teal osprey and then use DeltaChances instead of AuraChances

ok I fixed a few things lmao

well I'll need a bit more context on how BonusLuck scales with "rare" rarities, since I'm not sure what fits that title

does it scale uniformly or does each "rare" rarity have different bonus luck multipliers

local AuraChances = require(game.ReplicatedStorage.Modules.AuraChances)

local function deepCopy(original) -- function from roblox docs
    local copy = {}
    for k, v in pairs(original) do
        if type(v) == "table" then
            v = deepCopy(v)
        end
        copy[k] = v
    end
    return copy
end

local DeltaChances = deepCopy(AuraChances)

local BonusLuck = 5

local RarityMultipliers = { -- example table
  {Name = "Unique", Multiplier = .9}; 
  {Name = "Devil", Multiplier = .7}; 
}

for _, chanceTbl in RarityMultipliers do
  if not DeltaChances[chanceTbl.Name] then warn(chanceTbl.Name.." is not a valid rarity") continue end
  DeltaChances[chanceTbl.Name].Chance *= (BonusLuck * chanceTbl.Multiplier)
end

what about this

Devil takes 0.7 of Bonus luck, Unique takes 0.9

if you set multiplier to 1, it'll multiply the total bonus luck
