The rogue skill upgrade Eliminating Blow's description says :
Foe AOE: Shaken for 12s (which is an addition to the tooltip, from the regular skill)
The description further says :
(Eliminating Blow) - Enemies near the target are Frightened from the attack.
Make up your mind, are they Shaken of Frightened ?
Shaken: -5 resolve, -3 power levels
Frightened: -5 resolve, cannot use hostile spells or abilities
