Most ogres in Oggok are indifferent to me in wolf form. Fuga on the other hand scowled at me (but did not see through invis). She was red to me at 52, which would put her level at 55+. If you're travelling through Oggok in wolf form, avoid the shaman guild.
i remember happily prouncing through oggok as a wolf back in the day, and then all of a sudden TWHACK THWACK THWACK and i was dead. they hit pretty hard for being shamans.
