Tooth half of key from random event

2004Scape

the mysterious old man just popped up the random event, and he gave me a treasure chest which had a tooth half of a key in it… i was just curious what the chance % was to actually get that roll

I’m having trouble finding the drop table for the casket. The casket itself is a 76% chance, and I see a commented-out section of the code with drops for the casket which implies that a key half is 1/150 for each half, which would be about a 1% chance to get a key half from an old man, but that’s just from the commented-out section. The real drop table may be different.

thanks man i appreciate it! i knew it had to be some good luck

code for casket from github

1/128 for specific, 1/64 overall seems
