Type Active Max Lv 10Attack Type Weapon
SP Cost10 TargetEnemyRange1 cells
Required ForHiding (Lv 5), Snatcher (Lv 1, Rogue)
EffectAttempts to "steal" an item from the targeted 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, Frozen and Stone Cursed monsters cannot be robed.
The formula for stealing is: DropRatio*(DEX - MonsterDEX + 10 + 3*SkillLV + )/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.

EffectToggles 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 (except certain Rogue skills) and do not regenerate HP or SP.
The hide effect makes a character invisible to other players and monsters. This stops skills and spells that are targeted 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!).
Attention Concentrate, Ruwach, Detecting and Sight are all capable of revealing hidden characters. Consumes 10 SP for casting and continually drains certain amount of SP while hiding.
