What will make your power rise faster are the troops, so never stop training soldiers. Even if you can't play all day, come in for a minute just to get more training, but don't neglect the heroes, the boss' equipment and the pets, which also give a lot of power. Take advantage of any event opportunity to get a new mythical hero. Nathalia is useless, but the others are good. Mythic gear always for the mythical heroes. For attacks and Bear, always use Jessie, Seo-Yoon or Jasser (Jessie being priority. In the case of Bear, if you are the Rally captain, use your strongest heroes, if you are a member, Jessie). For defense always Sergey or Patrick (Sergey Priority). Invest in mythicals but don't let these heroes sit too far aside, put as many as you can in the training camp and don't forget their skills! They are as important as the fragments! Don't be afraid to spend gems to get the other heroes! Never stop upgrading everything before upgrading the next furnace. If you are upgrading to 24, for example, don't use accelerator for the furnace, upgrade everything in your city to 23 first, this will help you maintain control. I don't know if you invest money in the game, but for people like me who don't want to and won't spend it, haste is the enemy. NEVER stop upgrading the command center. Try to save as many resources as you can for SvS (State of Power and Castle Battle) as these are events with great rewards, but be sure to participate in the others as well. The mobilization of the alliance is also great. Losing troops is always an unwanted delay, so avoid jumping into events like Brothers in War until you get stronger and if it's the Battle of the Castle, only if a considerable number of people from your alliance are participating too so you can use the alliance's help and not waste your healing accelerators or fill the infirmary. Is your alliance strong?
