The game gives out such little rewards.I finished a quest worth around 60 primogems and it was such a hard puzzle, most puzzles in genshin never give out any hints or any better rewards.I had to resort to going on YouTube to finish most quests because of how insanely hard they are. It's insane how you have to spend 200 dollars for a character you really want and 1,000 for the weapon and character and it's tempting to put in that money but please don't it's not worth it.
