Many of the skills that you learn in Dragonspyre are very applicable in Celestia and Wintertusk. Now you probably think I'm going to launch into boring stuff and you're right! It's boring but makes the game ever so much more fun if you're not dying every 5 minutes!
I'm just going to launch into some of the tips that I've talked about before but with Wintertusk in mind. Forgive me if the tips seem simple at first. (There is room for finesse)
1) Always check the type of bad guy you're going up against and ask for your friends to let you have a moment to adjust your cards. This helps in case you need to throw in some converts in order to turn your spell into a school that is most damaging to the enemy. It also gives you a chance to load shields that are best against the enemy.
2) Buy or get an extra deck from your bank if you only have one deck equipped.
3) Set one deck up for boss battles. (In Wintertusk these generally require heals and dispels and converts)
4) Set up one deck for normal quests.
My recommendation for a quest deck is 3 of your lowest level multi-hit spell, 1 hit-all damage-over-time spell 3 single blades and gargantuan in your treasure or gargantuan in your regular deck if you've learned it.
Quick hard hits from spells like gargantuan Blizzard and gargantuan Meteor are very effective. If each person in your party does the same you'll blaze through the bad guys in two turns.
If you are an Ice wizard... (can I just say here "I'm sorry!?") Ice wizards are just plain out of luck in Wintertusk. Even if you carry converts you'll generally die before you get to use them so you pretty much need to quest with a Fire, or Storm wizard.
Adapt or die
Some of those that can afford the extra cost can purchase the fire amulet for their ice wizard. However, you can't just go out and start throwing fire spells in a serious battle and expect to live unless you use the crafted fire/ice hat from the crafting guy in the Grotto in Celestia. That fire hat will give you enough accuracy and critical to make throwing fire spells worthwhile. You'll also notice something a little odd... your fire spells will fizzle less than your ice spells EVEN though you'll have 10% more ice accuracy AND despite your ice spells being 5% more accurate from the base card.
You may also find that you want to equip boots that give you an accuracy boost for all spells. While you lose a little on the tough-plus for spells you at least don't fizzle and die!
With my new setup I can finally solo Wintertusk with the odd exeption of some cheating bosses.
Share your experience with how you deal in Wintertusk and if you have any special spells!
