I put the points nto Dire Wolves in order to boost the health of the grizzly. IIRC I mostly used the grizzly and poison creeper to tank. (Well the poison creeper is not exactly a tank, but he sure keeps the heat of you and your grizzly.) Volcano was used to finish off the bosses. I didn't really use the wolves to fight any tough battles for me, though in my guide, I quote someone who did. Incidentally, The Amazon Basin is a great website for DII--lots of great info and nice people there.
I just noticed that, even though I am not working on my Grizzly it's still getting the health bonus from Dire wolf. So I can actually keep the Grizzly as one big tank but he won't be doing any damage at all. I saw that quote in your guide. Funny thing is, I used the Grizzly fighting the Ancients but that was in normal difficulty. <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
Edit:
Here is a quote from your guide.
These builds require patience and skill to play. As you play them you'll develop the skills naturally.
I kinda feel the same way about my build, it's more about play style.
The biggest factor in my build is to keep freezing everything. Slow down their attacks and it slows down their damage. It's what keeps everyone alive, especially the Dire wolf.
I fight as a pack with my wolves and I am always in the middle of the battles. With three of them forming a wall, you have the time to cast spells and stand your ground. I cast Arctic blast across my wolves and through everything coming at us. I now have Hurricane circling us all and causing extra damage.
Even with Hurricane as a freeze, it still buys you more time. I can keep summoning more wolves as they drop. While letting Hurricane take the place of Arctic blast, it allows me to have the summon spell up. But in good battles I like to be casting all three.
Don't get me wrong, there are times we are all scattered and everything gets crazy. <img src="/ubbthreads/images/graemlins/eek.gif" alt="" />
The key is to still stay with your wolves and fight as a pack. If you leave them alone and don't freeze things for them, then what is the point in having them. They won't last long enough to be of any use, so you might as well choose another path.
Not sure if this is good enough to get me through Hell. Maybe that's why people keep saying to take Armageddon. <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" />
