Spending renown on max level mercenaries

with renown i prurchased a number of upgrades for my maxed out character Xyrella; each of these were spent on xyrella’s Radical Radiant wand on the fly out page; it now shows that i have +28 more damage and gives -10 attack more. On the main character page it has lvl of my radiant wand 5 and none of the upgrades i made seem to have applied but the radiant wand can now be leveled past 5. why did it let me upgrade the other with no effect as i thought i was supposed to do when the other (radiant wand 5) is what needed to be upgraded? please refund renown or reapply to the correct spot.ty

It’s not a bug. You leveld a Treasure of Xyrella, wich you get after a win against a Mythic rush boss (you can choose from 3 Treasures, which are random from the 6 on the page) and then you get the buff.
Also when you go to the Page on the top you see it’s called renown Treasures… for further informations you can click on this page on the top left corner on the “?”-Symbole.

If you want instant buffs you need to level the Abilitys or Equippment on the first page. The second Page (Treasure Page) is only for buffs which apply in a Mythic Rush, after a boss.

I am having an issue with the abilities and equipment from the first page. I have Grommash maxed out and I have leveled up his blood fervor and gorehowl using renown, but when I take him into bounties they show as being regular max level. When I select my party, I can even see him show up with 12 attack in party, but when I select him specifically, he has the 13 attack he should have. Any idea what I’m doing wrong?

extra renown upgrades are only for mythic mode bountys
