Thief Skills

This section covers all known information on the various Thief Skills.

Detoxify (Envenom L3+)
Max level: 1
Type: Active
SP Cost: Unknown
Target: 1 Player
Range: 9 Tiles
Cast time: 0
Cast delay: 1 second
Duration: Instant
Effect: Cures poison status on target.

Double Attack
Max level: 10
Type: Passive
Effect: Gives chance to hit twice with a single swing of a Dagger class weapon equal to 5%*Skill Level. In the case of an Assassin wielding two Dagger class weapons, it applies to the right-hand weapon only. It is also involved in the off-hand damage of a Katar according to the calculation ATK*(1%+2%*Skill Level).

Envenom
Required For: Detoxify (L3+), Enchant Poison (L1+, Assassin).
Max level: 10
Type: Active
SP Cost: 12
Target: 1 Enemy
Range: Melee Range
ATK Type: Poison property, Melee, Physical Attack
Cast time: 0
Cast delay: 1 second
Duration: Instant
Effect: An attack that adds 15*Skill Level damage (unmodified by Armor and Vit Def) to your normal damage. This bonus damage is always inflicted, whether your character lands a normal hit or not. Envenom has an unknown chance to inflict poison status on target (rising with skill level? Unknown). Undead and Bosses cannot be poisoned.

Hiding (Steal L5+)
Required For: Cloaking (L2+, Assassin).
Max level: 10
Type: Active
SP Cost: 10
Target: Self
Cast time: 0
Cast delay: 1 second
Duration: 30*Level
Effect: Toggles the hide effect on the character on/off. Toggling the hide effect off consumes no sp. Hidden characters cannot move, attack or use any skill and do not regenerate HP or SP. The hide affect makes a character invisible to other players and monsters. This stops skills and spells that are targetted at you from working (those with casting times fail) and anything attacking you stops (assuming that their last hit doesn't hit you and reveal you!). Area affect skills and spells can still hit you. Insects, Demons and Boss monsters are not affected by the hide affect. If you get hit by anything while hiding, you will be revealed. Improve Concentration, Ruwach and Sight are all capable of revealing hidden characters.

Increase Dodge
Max level: 10
Type: Passive
Effect: Increases flee by 3*Skill Level.

Steal
Required For: Hiding (L5+).
Max level: 10
Type: Active
SP Cost: 10
Target: 1 Monster (non-MVP)
Range: Melee Range
Cast time: 0
Cast delay: 1 second
Duration: Instant
Effect: Attempts to "steal" an item from the targetted monster. Only items dropped by the monster can be stolen. A successful Steal attempt will not affect what is dropped when the monster dies. After success, it is not possible to Steal again from the same monster. Boss monsters and those affected by the Frozen and Stone Curse effects cannot be stolen from.

The formula for stealing is believed to be AdjustedDropRatio = DropRatio*(Dex + 3*Skill Level - MonsterDex + 10)/100 where DropRatio is the percent chance of a particular item being dropped. If the result of the steal check is lower than the AdjustedDropRatio for an item, then it is possible that item will be stolen. I assume some random method decides which item is actually stolen out of the short list of possible items.

Find Stone (Thief Job 20+ or Assassin/Rogue):

Range: 7 Cells
ATK Type: Neutral, ranged, physical
