Grand Ultimate Dragon Tactic Guide (revised and improved based on your tips :D)
Thank you all for your recomendations and tips in the past, I have put together this guide based on your tips!
First off I want to say this: if you are trying really censored the hardest levels to get ledgendary levels, you are looking in the wrong place. You can get ledgendary gear anywhere. I recently just got a Bewilderbeast sheild from the first level of the training course! Another way to make sure you get really good weapons is to try to collect rare weapons to fuse into an epic one and so on.
If you are thinking of getting a new dragon, Skrills are always a good choice because of their range, Skrills also have a "lighning coat" or something like that that can deal some damage, just bring him into the center of the fray and LET EM HAVE IT! Monsterous nightmare does something similar, but I think the skrill might have more power.
DON'T try to get a Zippleback or Tunderdrum. Unless you don't have too much patience, you could go around finding coin and video chests because they have a pretty good chance of giving you Zippleback, Gronkle, Nadder, Whispering Death, and Thunderdrum eggs. I have a bunch from those chests.
Now, try to level up your viking, eventually he/she will have so much health that with the right moves, you may never loose a battle. Make sure to have some armour on. Even if you just have the common stuff, thats fine, but armour will up your hp and defence.
Now "it's time to put the 'tactics' in Dragon Tactics" -CrystalMoonFang
This strategy I got from reading Crystalmoonfang's guide for dragon tactics. So you want to have two "sniper" dragons (dragons with long range, a skrill is one) and one "tank" (strong dragons with good health and attack). If you can't get a skrill, I recomend using a Nadder. Stormcutters and maybe hotburples are good tanks too. Have the snipers benind your tank. Attack with the tank first, and have your snipers deal some ranged back up.
I have found this quite usefull. It's a good idea to try and scout a level upon entering for the first time. You may be able to form a plan on moves and when to block. If there are areas with a lot of enemies in one area, Zipplebacks have a great attack for that, or you can use the skrill. Always try to suprise attack as many enemies as possible, this will prevent them from dodging. With your snipers , try a "hit-and-run" technique where you hit the target, and if you don't finish it off, move away. You can't move towards the target to do this. You have to attack from your place, and fly away so that your sniper doesn't take too much damage.
If you're thinking that you should just keep ending your turn until you get a special attack or move, that is a TERRIBLE IDEA!!! The enemies will just go on alert and move toward you even when they can't see you. Save your attacks for when they are really useful. If there's a really dangerous enemy, use them on him, but if the attack is ment to target multiple, try and save it to hit more than one. Again, Zippleback's are great for this.
Now if you are having trouble picking weapons, this is good for you. I always like swords, but some people like other ones. If you use a sword, the best way to utilize the sweep is to make two enemies alert on you, then block. Once they move in front of you, finish them with the sweep. If you use an axe, then try to do a sneak attack and hit the target with an axe throw. I don't really like maces though. All the bonous attack does is have greater attack and stun. If you just need a super attack this is a good one, also if you are trying to stun a character, but I don't use it too often.
If you are trying to get past a level but one of your characters keeps getting knocked out, try to have at least one who has some sort of heal power. That or have one with strong health and a regenarate (like a whispering death or triple stryke) to act as a sheild.
Now if you want to know some good dragons, here they are:
Zipplebacks (strong attack)
Skrill (ranged attacks)
Thunderdrum (strong basic attack)
Nadders (fast and ragned attacks)
Stormcutters (strong health and attack)
Deathgripper
If you are trying to level up your dragons, stable quests are good, and so is that eel roast game.
