As Adler said - You need to be able to gather before you can start thinking of having a chance at HQ. So 0% chance well.. you do the math.

If your equipement isn't that good yet, I would try to concentrate on the first steps - Being able to gather 1 star items HQ so that you can get your new tools and Forager's hat.

That should help.

For 1-star you need 370 Gathering and if you want HQ 1% (to unlock the chances) you need 332 Perception.

The more the better.

I think it's equipment iLvl 55 first, HQ of course. Then you will have to meld Gathering, Perception and GP (you can use food for that last one, once you reach the minimum numbers on the first 2 stats)

Then you can try to gear up so that you can "attack" 2-Star nodes.

This is where Adler stated you need 408 Gathering. Same here, if you want to unlock the HQ chances, you would need 389 Perception.

After that, you can try to get at least 600 GP since 300 goes first just to unlock the node. Then if your gathering number is decent, you should get let's say 89% gathering chance (which I have atm on my Miner ^^) so your 300 other GP left, you could use the 30% HQ boost, giving you a base of 31% chance to get HQ.

Remember it's not 100% gathering, so you might fail having even NQ.

But for our sake, it's HQ we are striving for.

Good luck with your DoL.
