While energy is the only resource you need to keep playing this game, the only reliable source to get energy is MAGIC WELL.

• Currently, every 30 min you can claim energy from your MAGIC WELL.
  
• You can do it up to 9 times. You can stack energy over you "max" energy bar. Usefull to have longer play time sessions.
  
• Then you are forced to pay gold coins to upgrade your MAGIC WELL and to be able to claim again.

Be careful with stacking energy, if your character get a new level your energy bar will be filled again, unless you have more than your max energy : you will then get no benefit.

Pro tip : you may spend all energy you want at farming MARKET HOS, if you can. In that case, providing ~0 XP, thus providing no new character level.

• Cost upgrade is increased by a fixed amount of +565 gold coins.
  
• After each upgrade, amount of energy you claim every 30 min is increased by +15.
  
• Total energy you can claim before you have to pay gold coin again, is thus increased by 15 * 9 = 135.

So on average you always get about same amount of energy per spent coins.

And you always have to produce about same amount of gold per used energy to be able to upgrade to next level of MAGIC WELL.


Farming item, monster and HOS are not enough by themselves to produce enough gold for next level of MAGIC WELL.
To be able to produce the extra gold you need, there are only few options :

• extra gold from quests, globally low amount (~130 gold/ruby rate, slowly going down) AND... you have less and less quests as your characters progress and get levels, moreover quests require more costy items or collection activation. Always ~4 quests at same time at beginning. ~2 quests after level 40. Currently 0 at level 52.
  
• extra gold from collection activation. (I am working to find out a good way, but it is unlikely to be sustainable)
  
• extra gold from Christmas event (huge amount of gold and rubies here, but it will end soon, and most or all players will be shocked or blocked in Wanderland once it is over !)
  
• gold from GOLDEN IDOL, but really extra low ruby to gold coin conversion rate, you better spend rubies on extra chest loots, that will save you from farming for same weapons if you don't get wanted items, thus saving more energy/gold at a better rate per ruby. This is especially true for expensive weapons required for gremlins.
  
• gold from real money shop ($3 for 4k gold, $100 for 180k gold), you will see that this game is not really free nor cheap, if you want to keep playing it !
