Hi Everyone,
Thanks for your posts, I faced the Elite Jedi again in Corella and it was a Jedi Shadow who performed this ability, from my guess and understanding could it be "Time Slow" the very last move a Shadow learns on the skill tree.
Yeah he just jumped once and the whole damage dealing pulsing thing begins for about 5 seconds, I tried to watch out for the Blue bar as he performs or any abilities I'm suffering but nothing completely blank.
