Hi everyone, this guide is there for explaining hidden mechanics of the game, such as the luck, traits or things developpers dont explains well !


I'll try to provide as i can code from the game, so, in that way you will probably understand more well, and also check my own work and report me my mistakes :). For those who have acces to the scripts, i'll provide you
the names of scripts used, you can so make a deeper check of my work.

Lets start.

I. Luck and luck trinket

There's a lot of rumors concerning this mechanics, and if by now, lot of peoples know that its only works for the carrier of the trinket, i have to say it one more time :

>>The luck trinket (without taking in consideration the quality) only works for the carrier of the trinket, so, if a member of your team runs it, let him open chest first.

Why that ? Because of the way of how buffes works in Vermintide :

Interactions.lua :
[code]local buff_extension = ScriptUnit.extension(interactor_unit, "buff_system")
chance = buff_extension.apply_buffs_to_value(buff_extension, chance, StatBuffIndex.INCREASE_LUCK)[/code]

As you can see, the buff is applied to the "interactor_unit", so in a more clear explanation, to the guy WITH the trinket.

Now, how that's works ? What is the base chance to spawn a dice in a chest ?

Interactions.lua :
[code]local chance = dice_keeper.chest_loot_dice_chance(dice_keeper)[/code]

Here, the script calls another script : dice_keeper.lua and the "chest_loot_dice_chance" function

dice_keeper.lua :
[code]DiceKeeper.chest_loot_dice_chance = function (self)
	return self._chest_loot_dice_chance or 0.05
end[/code]

The game works with percentage, 0.05 is here equals to 5%. A chest have then 5% to spawn a dice. With the trinket your increase then this percentage of spawn to :
- Promo purple : 5.05%
- Green : 6.25%
- Blue : 7.5%
- Purple Halloween : 9.55%
- Orange : 10%

Note : I listed the promo luck trinket, but i never saw anyone using it, and i honestly dont know from wich promo this trinket comes from.
