Lambda Grinders

Does any one know the best Way to grind For lambda Grinders on NA?

I personally have been grinding 10* to swap for excubes, and exchanging excubes for lambda grinders and other needed enhancement items.

I got most of mine from the closed beta. I think Dark Flaz Elder gave me like 20 of them. Other 20ish I got from doing things on the ark quest menu.

As of now farming them is VERY hard because we literally only have the base content of the game. Might get more Tuesday, but who knows.

Trade the overabundance of 12* drops for them in the swap shop.

Sell the Nox weapons, trade the Sigma.

Trade 12 Star weapons. Buy 10 a week from casino. Do daily missions.
