I used mine on Doom for prestige reasons.
Used mine on Ghost. Only pulled her one other time since and that was 9 months or so after using the gem so I'm fine with it
Gave it to ghost. Guys, stop worrying about prestige. I'm at 12.5k and i'm ok with it.Use your rare resources on great champs, not prestige monkeys. You'll be happier
Used mine on CMM within a day if getting it. I regret nothing.
Pure prestige plays hurts. Sometimes I'm glad I don't care about it
