so i came back to the game. after played it some more after the update. new storage really streamlines the mana gathering. that plus unlocking just 1 extra mana seed plot and now ive found the real bottle neck to the grind is the fact you cant sell potions very easily, i had like 7 mana potions and 2 greater mana potions, total vaule of 130 gold but cant sell much very fast. only one npc can buy the greater potion, and most of the npc that buy, regularly only buy 1 or 2. one buys 3, but all the npc, except for one that buys only 1, 70% of the time decline. its super tedious. couple this with the fact that the the potion quests almost always need different color potions, and it just becomes the biggest bottle neck by far. like i say before, unlocking the other colors is a bit pricy but honestly wouldn't really be an issue of not for the potion selling bottle neck
also, game is buggy. ive had to start a save over cuz of a soft lock with the mana transfer and mana conversation not working. just an fyi
