Coldain Military Wristguard quest confusion

[Rygar]

Hey all, has anyone completed the Coldain Military Wristguard quest recently? The wiki walk through is here:
http://wiki.project1999.com/Coldain_...istguard_Quest

It just seems confusing where it no longer requires the Velium War Wolf Choker. So it appears quest goes like this...

1) Get 'Bottle of Karsin Acid' in Crystal Caverns, give to Erdarf in Thurg, receive Gem of Persuasion
2) Hand Gem of Persuasion in to A Frost Giant Wolf Tamer and receive the 'giant version of this gem' (not sure exact name of gem)
3) Hand 'giant version of gem' back to A Frost Giant Wolf Tamer to receive Giant Control Harness
4) Hand Giant Control Harness to Shardwurm Broodmother and then kill Korf Brokenhammer to loot your Coldain Military Wristguard

It just seems odd that you just hand the gem in twice to the same mob (A Frost Giant Wolf Tamer) without the wolf harness portion that is claimed to be removed from the quest line. Has anyone done this with success or is the wiki incorrect?

Any help is appreciated, thank you much!
