>>95193090it's the material to craft the heirloom for apex characters. normally if you use melee/holster you weapons, your character uses their fists to punch and do melee damage; however, heirlooms are a specific melee weapon for each character and when you craft it, said character will always use it when in melee state as well as having unique animations. most famously there's the wraith kunai. the normal pity is opening 500 packs, but the normal rate is 0.045%
a quick video you can skip around just to see the different animations for them (i dont think it's up to date but it works)
