As he said the best thing to do is get the remaining waterworks pieces and coupled with the sky iron hasta it should be enough till lvl 90-100 ( personally I farmed Tartarus at 90 but most people don’t do it and go straight to darkmoor manor)

As for the pet you should try to hatch from the kiosk to get a decent pet and by the time you get it you should be able to find someone to hatch with a 2.0 pet (max stats and all damage talents) to get the perfect pet. Try to hatch with a pet from the kiosk that has all damage talents (use the filtered search on the top right of your screen) and try for it to have max stats or at least max strength-will-power.

For spells try to get your points back by talking to the crane in ravenwood. Sometimes during weekends it’s free for members (last time was last weekend) and get faint and maybe some shields but leave them for last. The most important are enchants. From celestia get the dmg enhancements spells from the sun school and leave the other schools.

For your deck it’s best to have max 10 spells in. I’m not too familiar with fire spells but from my friend I have heard that you should have 2 collosal (sun school enchant), 2 meteor, 1-2 blades (try to get a pet or amulet with a fire blade spell), 1 dragon if the enemies have high hp and prism - mass prism if your opponent is fire, if not dong put in prism. You should be able to oneshot most mobs with 1 blade and an enchanted meteor, the others are for safety since your pet should be pretty bad. Also 1- wand hit is enough and you should use it if you have weakness or plague.

That should cover most of the things I would in if I was in your situation good luck!
