'The King of Fighters AFK' (hereinafter KOF AFK) features a mechanic called 'Account Stats' that grants permanent bonuses beyond individual fighter attributes. This is a vital component for clearing stages and content. You can boost these stats in several ways, but leveling up your fighters is the most straightforward route to increasing Attack, Piercing, Defence, and HP. The best part? These stat bonuses are flat across the board, regardless of the fighter's rarity. Gamemeca has crunched the numbers and compiled a guide to the fighters who offer Attack and Piercing boosts.

Q. How many fighters offer an Attack stat bonus?
A. A total of 27 fighters: 7 Legend, 8 Unique, 4 Epic, 5 Rare, and 3 Normal.

Let's kick things off with Attack. You'll see this stat climb every 10 levels. It starts at a 1% boost at level 10, creeping up to 1.5% at level 20, 2% at level 30, 2.5% at level 40, and 3% at level 50, eventually hitting an 8% increase by level 100. Remember, this bonus is per individual fighter.

Fighters providing Attack bonuses are spread fairly evenly across rarities: 7 Legend, 8 Unique, 4 Epic, 5 Rare, and 3 Normal, totaling 27. Priority should be given to Legend fighters like Shermie, Chris, Orochi Iori, Orochi Leona, Mary, Mai, and Kyo.

Currently, Mai, Orochi Iori, and Shermie are your easiest targets. These three are top-tier in the current KOF AFK meta and are likely already anchoring your main squad, so you'll naturally pick up those Attack bonuses as you level them up. A word of warning: Orochi Leona is currently locked behind premium gacha and rank rewards, making her a bit of a challenge to acquire.

Q. How many fighters provide a Piercing stat boost?
A. A total of 27 fighters: 10 Legend, 6 Unique, 3 Epic, 5 Rare, and 3 Normal.

Next up is Piercing, which is essential for shredding enemy defence. It’s a crucial stat to pair with your Attack power. Since the essential 'Wedge' synergy grants a Piercing boost, it’s wise to level up the corresponding fighters alongside your Attack-focused ones.

There are 27 fighters in total that offer Piercing bonuses: 10 Legend, 6 Unique, 3 Epic, 5 Rare, and 3 Normal. While the total number matches the Attack group, you get 3 more Legend and 2 more Unique fighters here. I’d recommend prioritizing Yashiro, King, Mr. Big, and Shen Woo. Yashiro fits the Wedge synergy, King the Endurance, Mr. Big the Encroachment, and Shen Woo the Rage synergy—all solid choices for their respective roles.

Piercing bonuses scale exactly like Attack. Stick to a simple rule: max out your high-rarity fighters first, then slowly trickle resources into the lower-tier ones. Eventually, you'll reach a point where you've maxed your Legends and have a surplus of EXP materials, so there’s no need to rush.
