Master of North Title

I want to max this title. But I have some concerns about that will I be successful. I wished we could use more then 3 heroes but the game doest allow us. So is it possible to h&h the dungeons? And what am I going to do in hm dungeons. Btw does cons last after you enter another level in duneons.

You can pretty much hench anything, but it's a lot easier to grab real people. Anet already said that they aren't going to add the ability to add 4 more heroes to make a 7 hero party.

Maybe this will help you with your dungeon questions, as there are 18 of them :O.

And what do you mean do the cons last after you enter another level....oh. The point blessings? No those don't.

consumables do not last when you zone.

You can H/H any of the EotN dungeons, but some are far more difficult than others. Also, some will pretty much require you to take fairly specific builds on either yourself or your heroes if you want to be successful.

I'd definitely recommend you use the link from Neo and read up on Wiki about each dungeon before you attempt it, including the discussion tab at the top of the pages. They will give you a lot of hints about how to handle the creatures you'll find in each dungeon.

Another thing that will help you out a lot in some of the more difficult dungeons in HM (Rragers, Vloxen, Ooze, etc...) is a healthy supply of Four Leaf Clovers and/or Honeycombs. They can remove DP from your H/H aswell as yourself and can be the difference between finishing a dungeon/vanquish and having to restart.
