I will share my inventory too.

constexpr uint64_t INGREDIENTS_CLEAR =        0xFF00FF00FF00FFUL;
constexpr uint64_t INGREDIENTS_ONE_NEGATIVE = 0x80008000800080UL;
union Ingredients {
    uint64_t value;
    char values[8];
    // use 0 2 4 6
};

so to add to invetories I can to this

Ingredients a, b;
a.value = (a.value + b.value) & INGREDIENTS_CLEAR;

to check if there is any negative i do:

(value & INGREDIENTS_ONE_NEGATIVE) > 0

what about repetable spells?
multiplying work’s too :star_struck:

(value + ((spell.value * repeats) & INGREDIENTS_CLEAR)) & INGREDIENTS_CLEAR;

Simply and fast!
