Sap

Sap is a level 12 rogue crowd control ability that incapacitates a single target for up to 1 minute.

Improvements

 * Dirty Tricks
 * Prey on the Weak
 * Shadow Dance

Tips

 * Sapping in a neutral town does aggro the guards.
 * Sap is an effective crowd control technique. Don't forget to tell the party which mob you are sapping, as any damage breaks the effect.
 * Sap does not cause threat, meaning that if you Sap a mob and then move out of normal aggro range, the mob will not attack you after the Sap effect is broken.
 * Mobs that are Sapped won't be tagged as your kill until you deal damage to them. Be wary of other players stealing your kill.
 * Sap can be useful in a PvP environment, to even out a 2-on-1, to take out a Shaman's totems before you fight them, to capture a flag quickly in battlegrounds, or even after a Vanish. Remember, like all crowd-control effects, Sap is limited to a reduced duration in PvP.
 * Sapping a player of the opposite faction will turn on your PvP Flag. Be wary.

Comparison to Paralysis
Upon release, monks were given a crowd control ability called Paralysis. Like Sap, this causes an incapacitate effect up to 60 seconds long, but was considered a magical effect that could be reflected, grounded, or dispelled. In patch 5.2.0 it was made physical, increasing the similarity to Sap. This section compares the two.

Advantages of Sap

 * No 15 second cooldown, aside from that imposed by Stealth/Vanish or Shadow Dance.

Advantages of Paralysis

 * Can be used while the Monk or the target is in combat.
 * Can be used on any creature type.
 * Does not require a specific stance or form.
 * Does not require a melee weapon.
 * Reaches 10 yards farther.
 * Costs 15 less Energy.

Trivia

 * Sap is a basic Rogue spell in Hearthstone. The flavor text reads: "Rogues love sappy movies."
