so I tryed to upgrade jackal bandit backshield.
I dont know if its bugged but after 10 and you fail it wil decrease with 2 near 18 with 3.
I used more then 100 pluto +- 170 venurune and I made it to (11) my goal was 20 tho but even hard a hard time to hit 15.
while upgrading epics in the game I only need around 9-15 pluto to 20.
my Jackel bandit backshield is now (11) btw ;/
I think its a bit overkil and I think it should be like the other grades (honor) (uniqe)
