Here's a guide that explains the "Tank/Cannon" party setup. Illustrated Guide The info on tank/cannon is about 2/3 down, but it's worth reading the whole thing.

I was looking at the gear for your pets and wanted to make some suggestions.

Since one pet is now your tank the gear for it should be either illusionist or assassin. Illusionist if it's a magic based tank or assassin if physical based. The way it's set up right now if I recall is that only magic damage or physical damage is used depending on which is higher. For a relic try not to use one that has the opposite type of damage than you want or one that's split between magic and physical. So if you use a relic of the assassin you want one that only has the physical damage bonus or if you have a relic of the illusionist you want it to only have magical damage. This depends on what elemental tree you want your pet in.

For your physical attack pet you want only myrmidon gear. And for her relic you want one with all physical damage.

Edit: I forgot to mention I find it helpful to have five points of health in proficiencies in even non-tank pets.

all I did was buy like five droughts and when one died I revived it. PS kill the arch mage first then the archers THEN the others.

Do any of you have a level 29, 30 pet I can have?? I need it for my 3rd pet in my team.

sorry I have a 31 and a 30 but there my explore pets so I cant.. sorry :( but you can look at sales and buy one probably!

Kill the strongest ones the arch mage first then the undead night then finally the decay archer use potions to restore heath you don't need 3 slots I done it with 2 make sure you pet with the most heath in the middle and make sure it say alive.

None of mine with that level range are for sale, but I did a quick pet search and found 26 results that fit what you're looking for and there's a couple that are particularly inexpensive.

I'm not sure how you're supposed to do the pet search with the new layout side bar. But in case you don't know about it I'll explain with the old layout. Below Account and Explore you'll see a search bar. Where it says Users to the left of the empty field select for pets instead and then click on search leaving the field blank. This brings up a more advanced pet search. You can select level range, price range, and more. In this case though I would search just for level range and maybe price. Don't forget to check For Sale.

A good way to level up pets quickly is to send them on missions appropriate to their level and ability. That's what I do.

I beat it using a level 31 and 30 Zolnixi with balanced stat. I went out and I maxed my mana on level 10s and went to fight. I used one Finishing Blow on a Archer and another on the other. I then attacked one and when it was knocked out I went for the other. I did the same for the knights. On the Mage I kept attacking and using Finishing Blows whenever it was passed 50%. I did have to heal a lot but I was finally able to do it. If you still need 2 members I can sell you the 2 I used to do it and you can sell them back when you are done.

I have level 31s but I am only level 30 so I can't use level 31s
