Guild Wars 2

Do the nodes in the black lion chests like Orrian truffle simply give 1-2 truffles a day or are they like the sprocket and candy corn nodes that give upto 10-12 per day?

They act as a real node, so 1-2.
I’ve never used one myself, but based on the ones I have I am led to believe they are no different.

I got a lotus node from a BLC and it gives 1 or 2 a day.

1-2 a day only, can confirm.
