Doubt regarding 4* featured arena

Vedant_Mehta

If I have a champion and duplicate him through the 4* featured arena then do I get additional 275 5* shards and 24xT5 class iso.
And does it increase sig level by 20 because basic arena only increases sig level by 1

Basic arena is by 1 lvl while the featured arena is by 20 levels

It increases signature level by 20. But if your champ is already at sig99 you don’t get max signature crystal sadly.
Also you get the 275 5* shards and iso.

Thanks a lot @Greekhit and @TheD00M
