It's not removed. I just got a Golden Aquila Shield from a mutant snail with the following stats:
W.ATK: +0 (+15)
M.ATK: +0 (+20)
P.DEF: +64
M.DEF: +25
6% Boss damage
3% Allstats

There are other sources like insoya but their extractions compared to Fiel are lacking. I have stopped doing extractions myself.

This is so god dam broken. I can't believe that Nexon is making this a necessary change so people can kill those OP bosses.
