nope ... not if your less than GM magery, and cast it on the corrupted side of the rift ...
Might be worthy of a FoF question now than its been asked twice.
Until then ... less than GM magery ... won't get the effect any wheres ...
you CAN cast it with 0.0 magery ... on the shadowlords ... just need to be close to them ...
to get the cloak of corruption.
Just carrying the blackrock, however ... rng chance of infecting nearby spawn ... so
carry it only when your serious about, useing it on shadowlords ... or getting thru the dark wisp's "shields".
G'luck.
PS (get in
close)
