Hey Friendly,Ok, cool. I've actually played two life wizards past this point and you know what I did? I didn't solo. hehe. BUT, let me take a closer look at this and see what I might be able to do to help.
I have been playing on my level 22 life wizard trying to level her to 25 but battles take for ever! I am doing my best with deck set up but still not going well. Any tips because I really don't know what I am doing.
1- Life trap. This is an absolute must for Life Wizards. They suffer from the same low damage problem that ice magic does. Luckily for you, you can pick this spell up at level 10 from Mildred Farseer (the hidden trainer) on Colossus Boulevard. This is going to add +25% damage. Since you've turned 22, be sure to concentrate on using Seraph for damage. Seraph's base damage is 335 to 395. With a trap it is 419 to 494. That should almost kill everything in krokotopia.
2- Treasure Cards. I'm a firm believer in stacking your deck for success . . . and that means tresure cards. Either load your sideboard full of heals or kills and use them to add predictability in your game. If you know you need a heal and your sideboard is stocking with nothing but heals, then you know what to do. Or conversely, if you have 3 pips and need to cast a seraph, then if your sideboard is stocked with them, you'll know exactly what to do. Draw from your treasure cards and lay the smack down!
Now, these next suggestions have a little to do with your deck setup, but a little bit more about dressing for success. Some gear add cards to your inventory, and when you're talking damage percentages, every little bit helps.
3- Crown Clothes. If you can afford to get crown clothes, there's three items in particular that might be of interest to you. Footgear of Malediction, Ascendant Staff (or if you can hold out till 25--Phosphorescent Maul), and one of the pets with a dragonblade on it.
That combination is not cheap. The pet you will have to buy from a store with a gift card (as I'm sure you know, it's random what pet has what card, so check the gift card page often). The other stuff is going to set you back 5,000+ for the shoes and 2,500 to 3,500 for the weapons as long as they are still on sale. They'll all make things go faster for you, but it'll cost you real money . . . and in the end, you don't really NEED them, you just WANT them. So, do with that what you will.
4- Bazaar Sniping. There's nothing better than successfully buying the best clothes you can get for your level right when you get your level. Head to the bazaar at level 20 and try to find the gear with the highest hitpoint, power pip, and damage combination you can buy. Ignore accuracy and shielding stats for now. Don't forget to modify the colors so you get the best deal for the clothes!
Since you're theoretically wearing footgear of the Malediction from suggestion number 2, then these might interest you for your hat and robe slots.
Also note that you are right around the corner from another power boost with clothing. Level 25 has some amazing clothes available to you.
5- Secondary class. I don't know what your secondary is, but if you're seeking big damage at level 22, then perhaps the power of a meteor strike would interest you. It's a damage-all-targets spell available to you at level 22 in the fire school. It's base damage is 305 to 345 to all targets. That's almost as much as your seraph right there. Add a dragonblade from a pet and that jumps to 397 to 449 to all targets.
If you don't want to do that, then be sure to grab spirit trap from Niles which will give you a stackable trap to add to your arsenal. (You'll eventually want to get this either way as well as spirit blade at level 25)
6- Hurry through Krokotopia. If you stick to the main storyline in Krokotopia and don't do any side quests, then at the end of Krokotopia you will receive your life blade spell for completing the Krokosphinx. That's a whopping extra 40% damage to your life spells right there. That's huge. THEN go back and finish the side quests in Krokotopia, so you can get your levels.
And that's about all I got this morning (I'm out of time and need to wrap things up here LOL). Readers fill in the gaps please! /hug
