When you're leveling, the XP is a set pool like 5,000, and its divided by the units that are eligible to receive XP, so if you use a max lvl unit, or a friends unit, your other ones will level faster! On your airship, there are three spots that glisten, you can click on them 4 times per hour to get gold and other items! You can sell gem if you go to the team page and then hit 'manage' in top right, good to sell 1* or 2* gem Make sure to get your astrogems from the astroguide! Each time you get a new character you should be able to get some Gold is very important in the game and the gold dungeon resets to lvl 1 every day and cost very little in terms of energy, so you should definitely make sure to do it everyday When auto battling, you can click on a specific mob to focus Not all mobs have the same gem slots, so you should check to make sure you have the right ones (or the ones you want) Using a variant when awaking will make the evolved mob a variant - you only need to use on variant to guarantee it! best way i have learned to farm gold is through gems. Don't waste gold capturing monsters if you are trying to farm gold (1 out of every 5-6 captured monsters will return 1-10k gold, i did the cost analysis over 24 hours and i ended up at around -12k). Sell ALL of your gems after the farming period (with the exception of your really good gems, i.e. useful 4* with 2 buffs). The capture quests are really useful for getting gold as well. Plus, they help with other quests. Also, hold off on capturing until the last wave. Don't want to miss a rare/variant/legendary. I'm sure I'll add more but this is a start!
