What Does Aroma of Focus Do?
Consuming an Aroma of Focus gives you a buff that allows you to farm 700% more Soulstones and Specialties in the World Map. The only thing you have to remember when it comes to this item is to always check if a monster drops either Soulstones or Specialties before using an Aroma of Focus and farming them. Soulstones are collectible items that are dropped by some monsters in the World Map and some Bosses. They can be quite hard to farm without Aromas of Focus, but collecting these and completing a set per each Region in the World Map gives you a considerable boost in Combat Power. Specialties, on the other hand, are also collectible items that are dropped by some monsters and Bosses in NNK: CW. Once you’ve accumulated enough of them, they’ll also give you an increase in CP and some completion rewards so feel free to farm them as often as you can!
Where Do You Get Aroma of Focus?
The Aroma of Focus, alongside other consumable items like Energy Drink and Sweet Drink, is among the most elusive items in the game. But here are the several better sources of acquiring Aroma of Focus that you should regularly watch out for — F2P or otherwise.
Method 1: Basic Shop
You can buy Aroma of Focus in the “Potions and Consumables” section of the Basic Shop in exchange for Diamonds. Keep in mind that the price of the item increases every time you buy one, so try to buy only one Aroma of Focus on any given day. Also, considering the F2P Diamonds you can get in the game are so limited, I recommend buying the Energy Drink more often instead. Because Energy Drinks will give you not only more EXP when farming, but also more Gold and prize drops. Don’t worry, you’ll get enough Aroma of Focus from the other sources listed below!
Method 2: Weeklies
Unfortunately, you will not be able to earn Aromas of Focus through the Dailies System — unlike Energy Potions. You can, however, receive up to three Aromas of Focus every week through the Weeklies System once you’ve done enough of the necessary tasks required to collect them. Your Weeklies will be one of the very few sources of Aroma of Focus, so don’t forget to clear them every time they reset! They’re quite easy to do anyway, and you’ll need no more than five days at most to claim all of the awards if you’re an active player.
Method 3: Check-In Pass Bonuses
Another source of Aroma of Focus is the Check-In Pass found in the “Daily Perks” section of the Conditional Perks page of the Shop. You can buy this Check-In Pass as a complete F2P player with Gold, so be sure to purchase them after every two weeks in the Shop. While you may not get too many Aromas of Focus from the Check-In Pass, do keep in mind that you can also claim a Random 4★ Equipment Chest here!
Method 4: Events (Recommended)
Events are arguably the best source of Aromas of Focus if you’re a F2P player. Even if you don’t mind spending Diamonds or money for Aromas of Focus, you should still consider participating in Events as much as you can. After all, they’ll allow you to farm all sorts of other valuable items alongside Aroma of Focus, like Summoning Tickets, Weapon Upgrade Materials, Familiar Upgrade Materials, and more. If you’re a very casual player or a huge spender who doesn’t mind missing out on free farmable resources, then maybe look elsewhere. Otherwise you should definitely check out every Event held in the game.
