Which Gem ?Rank 4 to Rank 5 Rankup Gem ?Or Awakening Gem ?Confusing because you say 4-5 gem in Title, but then say you are searching for r5 (as well as r4) champs to use it on ?Also, if Rankup Gem, they have to be fully Levelled up to Max for that Rank, in order to use the Rankup gem on them.(it only replaces the Rankup, not the leveling as well)
