Anybody know the odds of getting timeless jewels? No luck in over 4leagues

I did 3 2ways and 2 3ways these last 2 days, killed every boss at least 4-5 times and haven't seen a jewel drop.

And haven't seen one in quite a few leagues honestly

Are they restricted to 4way or 5way only?
Do they have a very low drop rate?

(Took all legion nodes on the tree for what it's worth)

i don't know the exact drop rate, but its extremely rare to the point I would question the legitimacy of the claims it does in maps, if you get 2 lines of rewards in a 4/5 way you should get 1-2 on average.

Your atlas passives won't help in 5ways, just so you know. From my experience, you'll generally get at least a couple from a good 5way (4 lines of rewards or more). You have to focus on killing the bosses.

They can (with insane rarity) drop in maps.
