Thief

Last Updated: October 22, 2026

This guide is actively being worked on! Builds shown have been updated and reviewed.

Stat Distribution

Thief's main stat is LUK and secondary is DEX.

Armor requires 10 less DEX than the armor level.
Claws require the same DEX as the claw level.
A Dagger's secondary stat requirement can be either STR or DEX, and is 5 less than the dagger level.
Put just enough points into DEX to equip your gear. Everything else into LUK.
Plan out which daggers you'll use while leveling. Adjust STR / DEX accordingly.

Thief Skills

Nimble Body

Passive

Passive that increases accuracy and evasion.

Thieves still need some sources of accuracy to hit high evasion mobs like Zombie Lupin on level. Max this so you don’t need to worry about accuracy requirements.

Recommended Lv: MAX

Keen Eyes

Passive

Increases the range of throwing stars.

At max level, increases range by 200. Must max for Sin build.

Disorder

Active

Melee attack that debuffs the enemy’s Attack Power and Weapon Def.

While the def reduction will probably be ok for end game bossing, you’ll never use this during the early game. For Sins, only put 3 points for Dark Sight. If you’re a dagger build, you can dump remaining points here. Later on Bandits have the option of maxing this skill instead of Double Stab because Savage Blow replaces it as their single target skill.

Monster Defense Formula

Dmg = Dmg × 100Weapon Def + 100

Disorder lowers Weapon Def by a flat 1 at level 1, up to 5 at max level. Against Def 15, max Disorder (15 → 10) raises damage by 115 / 110 = +4.5%.

Dark Sight

Toggle

Toggle ability that lets you avoid taking touch damage.

Using this leaves you completely hidden from other players outside your party. Incredibly useful for navigating around the map without getting hit. High level players use this frequently to lower HP Potion costs.

Decent place to dump remaining points.

Double Stab

Active

Dit’s main attacking skill.

Actually a decent skill in first job thanks to its high skill damage. However, it still gets outshadowed by Lucky Seven in first job due to its myriad of benefits.

Max this if you’re going bandit and don’t want to SP reset in the future, but you’ll get lower rates than sin build.

Lucky Seven

Active

Sin’s main attacking skill.

Incredibly strong skill in first job due to the included 50% mastery and weapon multiplier being set to 3. Also allows jump attacking for better mobility. These benefits is why SinDit builds exist. For Assassins, this skill doesn't get affected by Claw Mastery so your damage range ends up being larger than any other class.

1st Job Skill Build

Thieves have the option between Claw and Dagger. Claw provides the easier time with leveling due to Lucky Seven's Weapon Multiplier being set to 3 and also having built in Weapon Mastery at .5. It's also harder to get KSed using Lucky Seven. In the current state of the game, I highly recommend both Sins and Bandits to go the Sin Build.

Stats Indepth

Thieves main stat is LUK and their secondary stats are DEX and STR. Thieves only have 1 viable stat build. Add enough DEX and STR to equip your gear, then add everything else into LUK.

LUK Scaling

LUK’s impact to damage can be calculated as

MIN = Skill Mult × Weapon Atk × 80 + LUK × Weapon Mult × Mastery + DEX + STR100

MAX = Skill Mult × Weapon Atk × 100 + LUK × Weapon Mult + DEX + STR100

Lucky Seven uses a weapon multiplier of 3.0 and its mastery is fixed at 0.5

Double Stab uses the Dagger’s Stab multiplier of 2.0, and its mastery is 0.07 at Weapon Mastery Level 0

Weapon Multiplier

Weapon	Swing	Stab	Shoot	Avg
Claw	—	—	x2.5 (100%)	x2.5
Dagger	x1.0 (60%)	x2.0 (40%)	—	x1.4

Accuracy

Accuracy decides whether your attacks hit. It's one stat used for both physical and magic attacks.

Accuracy from your stats can be calculated as

Common = DEX × 1.2 + Level × 2 + LUK × 0.6

Acc = Common4 + 15

Every stat here is your total, including equipment and buffs

Each attack compares your Accuracy against the monster's Avoid. Monsters that are a higher level than you need a lot more Accuracy to hit reliably, while being a higher level than the monster gives no extra bonus. Level is part of the formula too, so your Accuracy goes up a little every level even without adding stats.

Avoid

Avoid decides how often monster attacks miss you.

Avoid from your stats can be calculated as

Avoid = trunc(LUK3) + trunc(DEX6) + 5

Every stat here is your total, including equipment and buffs

LUK gives twice as much Avoid as DEX. Avoid doesn't help at all until it reaches a baseline for the monster attacking you. For example, Zombie Mushrooms require 52 Avoid before you have any chance of dodging them.
