Hey Batt,
It can be tough breaking through, but keep working at it. Once you do (break through), you'll find things so much easier. Something that will help is to look at your armor and jewelry you have now. Be on the lookout for armor that has good lower mana cost (LMC in the range of 6% or more for each piece), good lower reagent cost (LRC as close to 20% as you can find - looking for total of 100%), and good reflect physical damage (RPD as close to 15% as you can find). Any other stats, like Luck or Self Repair (SR) are just bonus, because you can use GM smith (for metal armor) or GM tailor for leather (preferred). Now, the difficulty will be finding all these stats on each piece you're looking for; but, be on the lookout so when you find one, you can grab it quick. Try also to balance your resists and get as close to max (70) as possible. The idea with a suit like this is that you won't have to worry about reagents at all, and you will use less mana when you're casting healing spells on your pets, and you will reflect some amount of the damage whatever you're fighting is doing to you! There are other benefits, but this is a good basic explanation.
Next, get a levelable weapon if possible... or at least something with mana leach as close to 50% as possible. Other weapon stats will help, but stay away from area of effect hits and discount any value for dispel - dispel is basically worthless use of points. With this mana leaching, you'll replenish much of your mana as you use it - nice, huh?
Next, you need to look at building up your dex to increase the number of hits/minute. Another benefit of a higher dex is quicker bandaging... meaning, you stay alive longer
Let's move on to jewelry. Look for +8 dex stuff. Do whatever you can to get dex stuff early on... if you can also get some strength bonus, do - but, dex is most important. If all you can find within your budget is Dex/Int, buy that... just get dex going, and make sure dex is as close to 8 per item as possible. Also, some modifiers to your resists, hit chance, damage modifiers, etc, are all awesome and bonus here. Too, there are other rings that can benefit you while building skills or that might allow you to control a better pet, etc. Consider picking up a ring/bracelet/earrings (maybe necklace if you don't use gorget) or two like this if you think it may help you down the road, and you can afford it.
Next, while building this gear list, work your vet up and use a mixture of vet/clerical spells to heal your pets... conserves on your mana, heals quicker, and cuts out downtime. Just be careful where you stand relative to the spawn. Once you get your mana worked out (I'm still working on that myself, but building mana leaching on a nice bow now) you'll be rocking the spawns. Then, you'll get into the special moves of your weapons of choice, and how they enhance your damage or other weapon effects. This can get pretty mana-intense as well... so, either buying weapons with mana leach or just building it into your levelable weapon will prove invaluable.
Good luck and feel free to pm me in game, and I'll see what I can do to help ya.
