Shuriken Toss now deals 100% more damage in the initial ranged attack, damage is no longer doubled when used on targets farther than 10 yards away, and energy cost has been increased to 40 energy, up from 20.
Glyph of Cheap Shot now increases the duration of Cheap Shot by 0.5 second, down from 1 second.
Glyph of Garrote now increases the duration of Garrote's silence effect by 1 second, down from 1.5 seconds.

So it looks like PTR ST is now dealing exactly the same damage at range as live ST, but for twice the amount of energy.
