How to use moonstones with Grinder?

[Warmonger]

Maybe I'm missin something, but have no idea what's about these "moonstones receipes" and how to enable them.

there pretty much spending moonstones to get a chance of a higher quality weapon (it wount appear as a option if it gonna make a legendary grind)

It’s usually on the screen on the same line as grind. I’m not sure about the default keys but for me regular grind is e and moonstone grind is q

Not all recipes have the moonstone grind option.

On top of my head, you can't use MG on 3 purple weapons to get a legendary, it has to be a purple weapon + 2 legendaries + MG for a guaranteed legendary of your choice (the purple weapon).

You can also use MG + 3 purple class mod to get a legendary class mod.

Will check, though I'm pretty sure I didn't see such an option.

Ahh, I figured out. Seems like you need A LOT of moonstones to enable grind.

It’s dependent on the rarity you put in.

It’s a lot at the start, especially with important backpack and ammo upgrades to get.

Sorry if it's kinda late, but that post just sums everything up from white to legendary rarity and all the different recipes for DLC weapons and stuff.
