Rarity of the Daddy Longlegs item

[arti]

Seriously, how frickin rare is this item? I've done multiple Chest runs with the D6, rolled the crap out of it, and I've seen everything but it. I'm short that item (and the Holy Grail) from Platinum. I'm fairly sure it drops from Treasure Rooms-wiki states that that's where it's placed in the pool.
Should I just keep doing runs until I find it? Is there some trick to finding it or is it just hilariously rare?

Let's just say RNG is a deeck. I've got the same problem with dead dove and prayer's card, I am two items away from platinum god (1 if I count ghost baby) but I can't find either of them

It's just the RNG, i've actually found that item a few times in the past dozen or so runs, but other items like that Parasite slug or Spoonbender from vanilla isaac are super rare for me.

I have the same problem. I can not find Daddy Long Legs for the life of me. I have done 3 or 4 chest runs, in which I rolled all the items several times, and I even used forget me know on one of the runs, to get some more chests and I still did not get it. I will still keep looking, but I think it is just super rare. For me, at least...
