The specials tab in the Store has packs for purchase w/ awakening frags (frags can be farmed in the upper lol levels 11-13.) The packs level up a LoL in stages. The awakening shards randomly drop in the LoL 11-13, but those packs allow you to focus on class specific. Between LoL 10, 12 & buying packs.... you'll eventually get what you need. It just gets more expensive (resource wise) the higher you go. Costs millions of gold to evolve too.
Hope this helps.
Btw.... once you get all 5 Lord of lights maxed.... then you go through the upper levels something like 100 x w/ each to earn frags for a Dark Lillith.
