Frozen Wasteland

[Olevipoeg]

The yellow 3* bricks have become the rarest. G. & Cosmic LoL and now Cyborg Eddie use them.

I've grinded Frozen Wasteland probably about 25 hours..... the yellow bricks drop
anywhere from 10 or 14 avg.per 8 hour key (give or take.)

Try Labyrinth Dungeon for yellow bricks and its probably the best place to grind awakening shards also.
