The new life crystals are pretty sick.
Full mastery crystals was +160 mastery, full exp was +80% exp, now you get to use both at once at an improved amount. (+240 mastery, +112% exp)
Already had the full set of 16 exp and 16 mastery crystals, just had to extract them.
It took about 4 hours to mine all the crystals from the crabs to make them, and about 15b worth of sharps and magical shards.
