Grinding How to

You need to take a quest or a map that requires the use of the unlock skill. Example of quest with unlock:

The higher the unlock level required the higher amount of proficiency you will earn. However, you can't open all treasures.

Maps have the advantage that you can unlock treasures that are over 1 or 2 ranks above yours. So use that information to your advantage (For some reason that doesn't apply to quests).

Note: Failure rate increases if the map requires a level above yours. You lose vigor but not the map (So you can try again).

Early ranks

Venice has a good set of maps that require rank 1 - 4 unlock and that are also found nearby. So stock on maps at the archive and go around finding the discoveries.

Once you find all the treasures or discoveries, report them so you get more maps (Including the same maps you just did).

Remember you can use gear (like the clip and boots) to increase your rank.

Other ways to rank unlock:

• Shipwrecks
• Dungeons
