Hi,
1. Comestibles are food and water they let you rest whenever there isnt any danger
see next answer
2. see that tent button down the bottom? Hit that button to rest.
3. easy way to level up- Find a dungeon with some monsters you can kill easily, kill them then do not go back for 7 game days and all the monsters will have respawned so you can get some mroe xp. DO NOT GO BACK IN DURING THE 7 DAYS OR THE TIMER WILL RESET!
Easy way to earn gold- Make potions using the ingredients you find and sell them
- play cards in the inn saving after every win and loading back to last save after every loss (save before you start as well)
5. recall spell, check the magic shops, the one in mastras may stock it fif not the one in vastares willl definetley. The shop items respawn daily.
6. Have a sword or staff you can use for close combat. don't rely 100% on magic. When using magic have a stock of full mana/ strong restore mana potions and fortify magic potions as these increase your magic damage.
Hope you continue to enjoy this amazing game and just ask if you need help!
You have 20 save slots use them all. Save after every quest, save before going into a dungeon, save, save save!!
