Took @Ahri from Mastery level 1 to level 4 during this event!
I u
My teemo went from 1 to 5 just due to his skin alone hahahah
A new achievement for me: I got my first champ (and my favorite foxgirl) to Mastery Level 5 this morning! Unfortunately the match was a loss, but I got an A- anyway. (I got matched with a 4 person party, and for a party of guildmates, they were not especially coordinated, and they were definitely not very map-aware.)
I also unlocked Ahri’s eternals before this match, and I completed 3 of them!
