Just tried dualspeccing on the PTR (never liked holy but with the OO5SR change it seems nice compared to disc now) and I've come upon a skill the shadowfiend has I've never seen before...
I never really looked at the tiny pet frame of mine when shadowfiend was active on live but did it always have this skill?
The tooltip translates into:
Creeping Shadows (?)
30 yards/meters range
Instant 6 Seconds Cooldown
Crawl through the shadows to target enemy and increases the damage done to this target by 30% for 5 seconds.
Never really seen (or noticed?) that before, but it reads like a blink ability, and as I've seen a blue poster saying they are trying to fix the annoying mobility issues of the fiend I thought this may be it?
