Uth Rune Questions

Since I've got no friends, can you farm a stack of uth runes for 1 golden avia feather if you had enough players to participate in, in 1 single run?
I am so curious

 

Pretty sure it always drops 0-7 uth runes no matter how many players enter

 

yeah but you can get 2 dungeon keys if two players were attacking the guardian

 

someone answer

 

I've tested it already; the amount of runes is not dependent on the number of people present

 

every player gets the runes as long as they did the 15% damage

 

Yeah but the AMOUNT does not increase even if more people attack

 

wait im so confused. The rewards get divided or what?

 

Each person who does 15% damage gets 0-7 runes, but the amount between people stays the same. Say, if me and a friends do 50% damage each, and I get 6 runes, my friend will also get 6 runes. So the max possible runes from 1 feather is 42, with 6 people doing 15% damage, and it drops 7 runes each.

 

Thats crazy! thanks!
