Kingpin or Moleman
I have a 6* skill awakening gem. I have the 5* max version of kingpin, moleman, and aegon who are all duped.
I’m trying to 100% complete 7.3 and 7.4. Whoever gets the gem will also probably go to r4 first if I get a skill 3-4 gem.
From 7.4 I can get whoever I use the gem to r3. Moleman is going to r3 regardless of the gem.
