managed to lv10 but did not hit 2s annie, ls, morg cause shop wont roll em. also didnt get a single mana item all game which is hard when playing an invoker comp. also item rng was shit i was thinking if i shouldve played all 5-costs but then training sentinels (got warden, reaper, sage) portal held me back
