Essence, Shard, or Permanent?
So I currently have 2 tokens to upgrade a champion to level 6 I was wondering what is the most efficient way to upgrade (I have 0 essence, no shard, no IP) Should I disenchant all my champion shards, grind chests until the champ shard drops(nope), or spend ip to buy a permanent? Which is the most efficient way?(from 450 champs to 6300)
