From iRO Wiki
Stop (Alt: Stop) is an active skill exclusive to monsters.
Holds a single target interlocked with the user, leaving them unable to move, but still being able to attack or use skills and items.
- The effect is cancelled immediately if either the user or the target dies or teleports away.
- This skill works on a single timer that is reset only if the user or the target dies, if the Teleport skill is used, or if this skill expires. If multiple instances of this skill are cast on the target before the initial timer runs out, they will all wear off at the same time when it ends.
- If the player has the Teleport Menu open and presses Cancel, the effect of this skill will also be cancelled.
