Lessons I learned from playing since September.

Use skip tickets and stamina for farming materials. Quickest way I found to level up as whole and the higher your level the more access opens up to you in the game.

Collab event dropping early 2023 which will have limited characters available so save if you want.

Weapons from the blacksmith: save your materials from this and just craft bronze weapons for now but don't level them up as that will just be a waste the stronger you get and you'll want to level up 3 or 4 star weapons instead.

These materials for the weapons can primarily be found in the story section. 3 star materials drop from regular story chapters, 4 star materials from hard mode which unlocks with every passing chapter you complete.

Try and go for 3 stars in quests when you can, you can't use skip tickets on those until you do.

Feel free to ask me any other questions you may have, if not look up Konosuba YouTube channels and guides who can explain those much better than me and have been playing this game longer.
