- Magnetic Leap must be activated within 6 seconds.
- Magnetic Leap can be used on a different target than the one you grasped if the Allow Skill Retargeting option is on.
- Prior to the the 28 January 2013 update, this was a single skill where you first immobilized the foe, then pulled yourself towards the foe as a channeled activation.
