Ideas that popped into my head today.
1. Free agent favor should count towards renown. at 75 there should be a 5% chance at a increase of renown drops. At 150 raise it up by 10, by 400 a 20 percent chance you will gain renown from chest and or end reward drops etc. I think if your well known enough by the free agents especially that snob capshaw then you should have it reflect on the amount of renown you can earn.
2. Ranger capstone Idea- Bane of thy enemy.. You become a serious threat to any enemy that you target as favored. All weapons used gain the ability "Greater bane" And give a +4 to attacks and +2 saves against Favored enemies.
The archery one is nice and all but for those of us who prefer to use non ranged weapons it be nice to have a capstone like this. I mean it is for level 20s after all.
more to come as I think them up.
