Accuracy: Accuracy is a factor despite the nature of the skill. Leap Slam can miss.

Attack speed: Leap Slam has an attack time of your weapon's base attack time plus.55 seconds. Local attack speed modifiers apply to the base attack time of your weapon before the addition of.55 seconds. Global modifiers to attack speed will modify the speed at which Leap Slam performs. Leap Slam may seem slow when jumping small distances, but in reality, Leap Slam is simply always performed at the same modified speed regardless of the distance jumped.

Dual wielding: While dual wielding, hits are dealt with either the main or off-hand weapon. If one of your weapons is not compatible with leap slam, you will be unable to use leap slam.

Multistrike Support: Leap Slam cannot be supported by Multistrike.

The maximum jumping distance of Leap Slam is confined by a square rectangle centered around the attacker. This means that the actual maximum distance will be √2 times as long, roughly 41% longer, jumping diagonally as it would be jumping straight up, down, left or right. Since the duration of the jump is the same regardless of distance, you will also end up travelling about 41% faster that way. Flame Dash and Leap Slam seem to be the only two skills that work this way, all other skills have their max-range defined by a circle as one would expect.
