Hiya!
I lowkey might be in the middle of the lab (work) on one of the computers rn so can't hang around for too long asdfghjkl
But let's see what I can rustle up rq here~
First thing you're gonna want is a companion, you can put them in the party with your wolves and they DON'T take energy, unlike your woofs, so they're a great source of extra help at all stages of the game! Plus you can bond with them every set interval (changes depending on rarity) for rewards! I'll send you a furmus rq, they have Intersect as their special which is just straight up S-tier lol.
(A special is a move that the party member performs once its energy bar is built up. You gain energy by attacking, being attacked, or through some special bonuses/moves! But predominantly the first two, lol. Intersect has the user intercept an attack for another party member to block it for them but ALSO has the user dodge it, basically negating the attack, and then the user deals a critical hit against the attacker to return fire. Great stuff!)
Farming's a bit rough if you can't sit and water your crops and don't have the foods to pay the gardener, but I think I have enough of all the different gardener foods on me to send you three of each! (It takes 3 of them to pay the gardener, and they then maintain your crop fertilizer/water levels for 12 hours) That way you have at least one set of each food to pay them with. :) I'll also send you some low level seeds!
Your other main food source is going to be fishing. You get one trip every half an hour (can have up to 4 at once) and you spend a minute tapping the little ripples to acquire fish, and sometimes items! You can then either eat these fish raw or cook them, and I very much recommend cooking, it makes them into a food that gives you 20 stamina instead of 5! I'll send you some cooked stuff and also some raw stuff to get started cooking! (I don't have a whole lot of low level cookables, but I have a lot of cooked stuff for energy at least, hah!)
For pebbles, the best option is generally to grind for trinkets and sell them from your inventory, and later on my personal favorite is to run gauntlet! Once you have a good team you can generally get pretty far in gauntlet, and net a couple thousand pebbles per run! It's also much less intensive than grinding, since you just click to go to the next round. ;p
I think that's everything I can think of off the top of my head in regards to your questions??? A quick tip, tho, you can refresh battles to skip them! The battle is automatically calculate from the moment you start, so refreshing skips the animation! This is easier to see in gauntlet, as refreshing takes you to the end of round screen so you can move on, but it works the same everywhere! I know it looks scary to refresh on a battle in campaign and it takes you to the next explore encounter, but if you have any activities for 'find items' or 'kill enemies' you can see them go up if you won, and you can also monitor your inventory to watch your drops accumulate from it!
Be back in a bit when I'm less likely to get yelled at for sitting here asdfghjkl. Sending items now!
