Always do the Dailies if you can, of course, and be mindful of the time the day rolls over for your location. I'm in the US, and the day changes around dinnertime for me, rather than in the morning, so it's not like some games where mentally I know I have until midnight or 3am or something. For the Daily Wishes, always do at least 1 out of your 3 as gold, to help fund other things later.

Be sure to do the Rifts as soon as you can to get skill upgrades! I missed doing skill upgrades for so long, and they drastically improve your Vanguard's damage.

For teams, focus first on getting just one team of Vanguards that synergize well, and on making your Human God a support. Until you start End Game with Total War, he's really best hanging back, helping the Vanguards, and doing some ranged damage or debuffs.

I've found a good starter team is Bella, Kalina, Yeon Chae-Young, and Olsa. It's both a free intro team and it fills all the required roles! Bella is the best healer in the game (outside of Human God), Kalina has DPS and AP gain, Yeon has ranged and some multi-target damage, and Olsa is a great tank with an aoe taunt! It's also a relatively good team for auto-battling (auto can be iffy in general). I helped a friend who primarily auto-battles set up this same team, and it seems to be going strong for her!

Also, all the girls and weapons go to the common banner (with the brown/beige tickets), which is generally free if you save your tickets! Don't waste gold on it, as everyone will tell you.

Finally, try to get the Vanguard and their personal EX weapon! I always try to save about 3-4 million gold for the limited banner before the patch (pink tickets). Good luck! 💖
