I have been wondering if there is a way.

I seem to get lucky. I am 1 relic and cloak away from 5 5pc guard sets

But other people who have been playing this server since DAY 1 with me and who play as much as I do have a lot less then me and some even have more then me. I know some of it has to do with WB drops
But I have only received 2 Guard plans from WB that I needed. I have seen people suggest the stars on the bosses effects what drops. But I have no clue what those stars are for.

I feel bad for the people who have been trying to get their last champ relic or cloak for 2 weeks or more and keep getting sword plans. But if I got them all - is there something I am doing differently to get the plans easier. It could just be pure luck - both bad and good. But there is a slight chance imo that we could be doing something to effect the drops
