Tip: Using 2x Mastery Boosts in best choice of job

Hi mafiosos!

While playing the last regions in Italy, I came to find the next job result:

"Locate The Secret Archive Vault" from Region 7 in Italy

Firstly I got a bit suprised by that Grapple dropped there, it was quite unexpected. We may find it mostly as loot dropped while fighting ...

Though the main purpose of this post is to give some tip about the use of 2X Mastery Boosts.
I will refer to Italy, though this tip would be also valid for other cities. The recommendation is to unlock all regions ASAP. Once we open them, keep diferent jobs ready to be progressed, and if possible at least one of them should be a job requiring consumables. The idea is to shorten the steps  needed to do to master the job, by using the boosts, so as  to use less consumables (and less energy - or even less stamina, if being fight path job ).
Even if there is no job requiring consumables, we would use the mastery boost in the job needing the highest amount of energy, to save on this precious resource.

For example, the job in the capture, "Locate The Secret Archive Vault" from Citta del Vaticano in Italy, requires 2 Hidden Charges per step done. This means that in the Gold and Ruby mastery, since the mastery increment is 2%, then each mastery level requires 100 Hidden Charges. These consumables are the most needed ones in the last Italy regions. So the tip is that when we come to get the X2 Mastery Boosts, we use them in a job like this.

Keep on the hard work of completing Italy, mates!
