So you just started the game and you really enjoying it while either going idle or staying up late to upgrade your crusaders on time, but you've reached a point where crusaders can't fill all the spots since you have limited spots for the complete formation and/or your DPS(Damage Per Seconds) is low and can't pass a certain area which in that case we call it a 'wall' .

We know that it's a clicking game but most of the formation out there doesn't involve clicking at all, mostly sitting back and let the crusaders do the job by letting them DPS through the areas.
I will try to include a basic formation that can help you get through the first reset, which is the toughest one, after your first reset everything will be easier.

First things first, what do we mean by 'reset' ? It's when you reach level 150 on Nate Dragon in order to use his ability which will reset your world, reseting your world provides idols, what are idols? It's the things you gain after reseting a world which will provide 3% DPS and 1% gold find each idol and by the time you reach your first reset you will usually have 15 idols ( 45%+ DPS and 15%+ gold find) which greatly increase your power early areas.
Also reseting worlds grants red rubies which will allow you to buy jeweled chests (an upgraded version of silver chest) from the shop, aswell as unlocking new objectives for more challenges and sometimes more rubies.

Each reset grants some rubies as we mentioned, you select objectives from the objectives menu, there are varuis of objectives, the harder objective the more rubies you get, some of them takes very long even if you unlock them so you may want to farm more idols in the free play mode to make it much faster.

Before heading to the formation, make sure to use these codes in order to gain much more DPS:
*Head to your backpack tab then click 'shop' near red rubies, there should be a box for the code*
NATE-932D-42BB-BOOM - Nate Dragon's Epic (200%)
BB49-JHAE-3891-U546 - Emo Werewolf's Epic (200%)
B53S-432A-9LTT-003J - Jim the Lumberjack's Epic (200%)
(register in the website for rare gear code at http://www.codenameentertainment.com/ )

The better gear you have on your crusaders, the better DPS/gold find you get, also the crusader with most gear/enchants determine your main dps.

For your first basic formation you need the following:

*
1
*****5
2 ******8
*****6 ****10
3 ******9
*****7
4
*

1. Detective Kaine, increases your gold found by 25% each crusader in the same column (100% with all four crusaders)
2. The Princess, increases your overall DPS by 40%
3. Natalia Dragon, increases Nate Dragon's DPS
4. Artaxes, The Lion, increases the front column dps by 65%
5. Jim the Lumberjack, increases the DPS of crusaders in the same column by 50%
6. Nate Dragon, your main DPS
7. Sarah, the Collector ( or any crusader with good gear on), your 2nd DPS
8. Sasha the Fierce Warrior, incrases the DPS fo the crusaders behind sasha by 40%
9. Khouri, the Witch Doctor, Heals the crusaders infront of Khouri also increases DPS of all crusaders around Khouri by 35%
10. Gold Panda, increases your gold found by 125%

It should look like this ( remember that dps change depends on the gear you have):
Note: Don't mind the DPS, I was at much higher area and used lower area to organize the formation.

Your main DPS crusaders are Nate Dragon and Sarah (2nd DPS), what you need to do is to level up all your crusaders to level 200 or until level 75/125 for the last upgrade and leave them, only level up your DPS crusaders which are Nate Dragon and Sarah, the Collector in this case, there's no need to level up your other crusaders as their DPS will be very low later on.

What you want to achieve before reseting for the first time is to get 7500 total crusader levels for 15 idols which is decent for your next run.

Emo Warewolf, is one of the best dpsers out there, he's cheap he's strong and goes well with various of formations.

I will first post my formation that I originally use to progress through the areas (Tri formation):

This is both my farming and progress formation, as all the crusaders buffs my ww.

- I use Natalia Dragon because I have 100% gold found gear on her, also 15% all dps
- The only dps there is ww, all the other crusaders are supports
- I recently added Prince Sal, the Merman because I got 15% all dps gear on him plus his ability 10% all dps
- The Dark Gryphon is nothing but to fill the spot for ww, I also have 10% all dps on him

Make sure to use the animals/non humans crusaders with the most increase of all crusaders dps if possible, to maximize ww's dps

Make sure to save up chests once you get them, doesn't matter if you store up to 100 chests without using them, you will need many chests once you hit a wall (stuck at a certain area). You can open jeweled chests once you get them because they contain no gold but buffs/gear.
Silver chests can contain gold/buffs/gear, mostly I'd say gold and the higher areas you reach, the more gold you recieve from the chests.

P.S: your first run will take long, so be patient, your next run will be much faster.

Thanks for reading, I will keep the guide updated and will add much more details and stuff in the future.
Stay awesome and penetrate through the areas!
