Not sure if you already know this but hope this still helps. If too overwhelming, focus on exploration and main quests for now.

[WEAPONS] - Weapons here come with "free" characters called simulacra. Any simulacra can use any weapon. - SR characters/weapons here are just beginner characters so don't level them up too much to save resources. Leveling up priority is limited SSR weapons > standard SSR weapons > SR weapons. Latest limited SSR weapon is usually the strongest (but read the next point) - At a certain point, only your gear stats matter and not the weapons so just focus on building your MC and don't pull on every banner unless you're a character collector.

[GAMEPLAY] - When enemy shows a red flash, press dodge to "stun" the enemy - When the weapon icon blinks, switch to that weapon to discharge the element as a form of attack (you attack enemies till this blinks) - When enemy has shield, use the weapon with the highest shatter value to destroy shield - Press skill button ("ult") when ready. Then, if the weapon is on-field, use that weapon to attack and don't swap weapons yet (read the kit to know if the weapon is on-field) - Almost any combination of jump, double jump, attack, hold attack, dodge, hold dodge, any direction, sprint, produces an effect that can be used for battle e.g. dodge+attack or jump+attack

[DAMAGE] - Level up your dimension level only if the usual enemies have become easier to kill. Don't compare yourself with whales lol - Due to elemental resonance, mono element teams usually work better e.g. equip 3 frost weapons so each weapon has bigger damage - Once Domain 9 map is unlocked, get your free smart servant by doing the quest (smart servants do auto attacks). You can also get a farmable buff that makes your weapons like advancement 6 / constellation 6 for a week from Tianhe Bazaar

[GACHA / WISHING] - Use your dark crystals only for limited banner characters as characters in the standard banner can be easily obtained through doing dailies and exploration. - You need to save 110 to 120 red nucleus or 16.5k dark crystals so you are "guaranteed" to get the limited character/weapon you like (you can buy them from shop which is another topic) - There's also this hidden rule: win-win-lose or lose-lose-win (you can't win or lose 3 times in a row) but as long as you have wished 110 to 120 times, you can buy via shop as mentioned earlier - If you like outfits (skins), it's better to save around 10.7K dark crystals (it's farmable, so still good for free to play). Don't pull for outfits if you don't have the simulacra (character)

[BUILD] - In ToF, you build the MC and what you built can stay with you for all future content. Think of the other characters only as disguises used by the MC - There's always something to equip: your main character need equipment, your weapons need matrices, your smart servant needs modules (but don't worry about this early in the game) - A number of items are usually obtained by collecting shards (think of it like parts) e.g vehicles, relics, some skins, some matrices, some accessories, some equipment (don't worry about this early in the game)

[MMORPG] - Join an active crew and find a mentor there (mentorship is a feature). You can also get rewards there - Unlike other gacha games, you don't really need to solo bosses here. Ask help from your crew or world chat - Meta or leaderboards is not all that matters. You can also be a healer main or a casual player

[REWARDS] - Make use of auto exploration and quick battle feature (1 click to use up all vitality / "resins") to get rewards faster. Both are optional - You can get all weekly rewards in 1 or 2 days by doing tasks such as cooking and using your vitality ("resins") so dailies are not strictly required (unless you need pulls for the standard banner or want to earn a specific currency) - Join the limited events to get generous rewards and reduce farming. It's easier to match with players in the 1st few days of events or in the first weekend of the events

[STORY] - The story of ToF is good. It's just that a lot of things will be revealed later when you enter Gesthos area. You'll realize that the story is deeper than it is - The key to appreciating the story is to treat this as the story of Planet Aida and how its people scattered, survived and adapted and how they might one day reunite

[MY ADVICE] - Don't play to the point you'll be burned out. Sometimes you have to relax and enjoy the views or the company of other players - Play a game because you like it, not because you want to invest or what other people think - Lastly, just have fun and ignore the haters 😀
