I feel bad closing this crap, I've never encountered such tedium. Are they deliberately making such a tedious thing to keep players in the game longer? It works against the desire to quit. The second swim, you need to kill golden rays, they just shoot me and I can't get through, and this is the beginning of the event.
I was procrastinating. There are 7 hours left in the event, I have 400 popularity, I'm not at home right now, and I have about 1,5 GB of internet left. I'm just f***ing amazed why all the events in Fontaine are so annoying.
Wow, and I thought I was the biggest procrastinator here)) I finished the 1000, but I didn't get to the last chapter of the story, and the story was the most interesting for me. Although I did enjoy killing fish)) It's a shame I didn't do the event earlier; if I'd known there was such a big deal with that 300k income, I wouldn't have screwed up. But honestly, I enjoyed underwater and killing fish in the pool. The selling part is kind of boring, and the potions were more interesting.
I always save events for later so I don't have to wait for the timers and can finish them right away, having collected all the goodies. I don't know about others, but they're such a boring piece of crap, not really an event, that the first time you play, you really don't care about all the goodies. Why can't they unlock all the attractions right away, like they used to? I thought the 1000 Nights of NTE event was the most boring, but at least you got to level 60 and then abandoned it, but Genshin beats all that. Seriously, games are turning from light entertainment into boring tedium these days.
Oh yeah, closing 400 points in the last half hour (thought I still had a day left) was a real joy. The 300k profit coupons really ruined the picture; I might not have closed even for a thousand points and lost the crown.
I give NTE a five, I also don't like the event where you have to kill 50 mobs in a second. They made a beautiful world, they should have just let you run around like in Gensha, or made a normal balance, otherwise 1000 mobs just appear at every turn, even on the story difficulty, it's annoying.
Can you tell me where I can put the extra money? Or is it impossible to exchange it anywhere?
I returned to the game after six months, played the event, and now I'm thinking of giving it up for a while.
ZAAAZZAVHAHAVHAAH
How do I advance from stage 3 to stage 4? I've completed all the side quests in the waters, and all the side quests except those that are completed during the event (like collecting coins and placing especially dangerous fish in the aquarium) have been completed. But I can't advance... and it doesn't give any new quests. I have enough money and all the talents I had are upgraded to the best of my ability. 💔 I don't know anymore, maybe I'm missing something.
What stage 3 to 4? If you're talking about the stages within the minigames themselves, there are only 3 of them. If you're talking about popularity level, you need to place fish and various items on the stands to increase popularity.
