The heroic Gianthold raid is called The Reaver’s Fate. The flagging is the same quests on heroic as on epic, but the quest givers are different. If you pick up the wrong quests you will still be able to run the quests, you will just not get flagged for the right raid. You also have to flag for Gianthold Tor and run it before you’re flagged.
Ok, so here’s what you do.
1. Talk to Cydonie to pick up the chain. You can also do this after running the first 3 quests.
2. Pick up and run: Madstone Crater (Blaze ar’Rhind), The Prison of the Planes (Nimbus Ar’Yorg) and A Cabal for One (Jorgundal ar’Grund)
3. Turn in the quests, then talk to Cydonie to flag for Tor
4. Pick up Tor from Crag, run it, turn it in.
5. Talk to Cydonie to be flagged
6. Pick up the raid from Agon Uruhond
And here is my flagging video:
That’s all folks.
Thank you for stopping by.
