Gumball and Dungeons: How to recruit all gumballs from mercenary camp without using gems

After you have unlocked Mercenary Camp you will see all kinds of gumballs in four different factions. You will need these gumballs for special events or for your airships or to fate link. But there are a lot of these gumballs and four different factions.
How to get them without using Golden Pots:

1. Warning: Use this method only after you have unlocked almost all or all the mazes and have Bandit gumball and its star rank is 3 or more.
2. You go to the Mercenary Camp and click on Condottiere gumball. You will see he is selling fragments for gumball fragments that you get from mazes. 5 fragments for 50 fragments of Adventurer, Swordsman, Priest, Mage, Bandit, Minstrel and other gumballs. You pay 50 fragments of other gumballs for 5 fragment of another gumball.
3. Condottiere gumball will change the faction which fragments he is selling now after he has refreshed his shop for 3 times. Each time the shop stays for 7 hours so you will have 21 hours to buy fragments for that particular faction. The faction change in this order Aoluwei's Blade first. then Canas' Enlightenment, then Ranger's Song and lastly Abyss' Roar.
4.  Use the fragments that you get from Bandit raiding that maze to buy fragments for other gumballs. This will be most effective when you have completed 80 DP quests on a few mazes. Because once you complete 80 DP quest of a maze, each time you Bandit raid that maze you will get 6 fragments of the main gumball from that maze. You will not need hidden gumball fragments to buy fragment from fragment exchange shop.
5. Most of the time Adventurer and Swordsman gumballs fragment will be needed to exchange fragments for two gumballs. So complete 80 DP quest of Adventurers Forest and Village of Hero first if you want to use this method.  
6.  There will be 6 gumballs fragments up for exchange at a time. Other then Adventurer and Swordsman gumballs fragment which will be used to exchange for two gumballs, the other four gumballs fragments will exchanged for fragments of different gumballs.
7. The gumballs that need 60 fragment to recruit are a bit of a special case. Because two of these gumballs only show up in the shop at time with their 5 fragments and which of them will appear when is random, so buy the when you see them.
8. Pick a faction. Let's say you picked Aoluwei's Blade faction. Now you wait till Condottiere gumball starts selling fragments of that faction. While you wait raid mazes and collect fragments of Adventurer and Swordsman gumball. If you have 50 fragments for each of them then raid other mazes for different fragments because you don't need what you will need. 
9. When Condottiere gumball starts selling fragments for Aoluwei's Blade faction you will buy the fragments you want. Keep repeating this method until you have all the gumballs you need 

Now this process is a long and tedious one. So brace yourself. 

How to get them without using gems to buy Golden Pot and using Golden Pot:

Other then this you can get fragments from Golden pots which you can get by:
