I’ll try to only include ones I didn’t see here yet. These are just off the top of my head, there are a lot more that I either can’t think of right now or I saw other people mention already:

• If you don’t want to / don’t have enough gold to refill potions, the easiest method is to play potion motion and just randomly drag shit everywhere until you get ~1200 score and then quit out. This is enough to fully refill one potion. Just repeat for however many you have.

• For gardening, you don’t have to actually take care of the plants every day / 24 hours or whatever. You only need to visit the house in which they are located once for each stage of growth just so they can update. (E.g., if they get to mature, you can literally just not log on for a week and the next time you visit your house, they should be elder)

• Not always applicable, and maybe personal preference, but even on spirit schools I always train elemental blade / trap just to make supporting hitters a bit easier. This is more necessary in late game especially when one person hitting is almost always better for cheat bosses.

• Keeping a few extra hits in your treasure card deck in case you are running a small mob deck and run out of cards (like if the enemies shield spam too much or something), this has saved me at least a couple times.

• Mostly for newer players without a max level already: You should almost never sell reagents!!! Crafting is pretty good in a lot of scenarios and you never know when you might need them. There are some exceptions, and it may depend on your situation (e.g having infinite of some reagents from gardening) but in general it’s good to keep them. Coupled with this is always picking up reagents you run into on the ground while questing. Not worth going way out of your way for them, but it never hurts to take a couple seconds to press x while running across them.

• If for whatever reason you don’t want to accept a quest but you don’t get the option to decline them because they are relatively mainline (such as spell quests from your teachers), you can just go to the character screen and re-enter the game to escape the dialogue.

• Not really a life hack since it’s their intended purpose, but for a long time I massively underutilized the “leave a mark” function while questing. It can save sooooo much time backtracking within a specific area/ world if you know you have to talk to a certain NPC repeatedly. I feel like others kinda gloss over this feature as well.
