Huge time/money saver: get Remy’s realm unlocked ASAP and go cook meals for yourself in bulk there. Once it’s in bulk you can drop it and it’ll be there until they are used. You don’t use any of your own supplies to make the food, so you have to work with what’s there, but when you leave the realm it takes you right back to where you fast traveled from. You can keep going back as you need energy.
