Enjoy the story first, that is the best part of this amazing game, and collect them all later if you want to.
I would HIGHLY suggest not to hunt them all while playing through the game, it takes a long time and catching them will be easier later on in the games with items you get during the main campaign and the sidequests. The spawns also different from grass spots, but even each individual spot, in case you have problems with finding a Nexomon with my guide, you can find a more detailed guide here, which is especially very useful for Palmaya beach: Most requested so here it is, sorry took awhile had to start a new game to put in as much details as i can.Skip all Vault Companions- 3:25All Vault Locations. So if you see a Nexomon in my list and can't find it yourself, you might not be far enough with the main quest for it to appear there. Keep in mind that evolutions of Nexomon can appear later on in the story on spots where they weren't before.
I make most of my choices based on aesthetics and not had much difficulty. Ive honestly found that most Nexomon dont make a huge difference. I hope this guide will be useful and that you'll find the Nexomon that you're missing. Are the non legendary dragons better to use than the Extinct Mega Rare mons like Divette, Rapnum, etc. BTW the names I gave each field sucks, I know that, but I added a screenshot to each one to make it more clear which field I mean. You will battle and lose to the dragon, but then a voice will be heard, and the statue will vanish, revealing a secret pathway. I'm pretty sure I'm still missing Nexomon, especially because while making the list there were more Nexomon added to fields I had already visited, but I listed all that I found. Note: The game developers have also added a feature of rewarding the people who catch all of the Nexomon, so make sure to catch everything, in order to keep earning Nexomon cases, which can give you very rare Nexomons. Its in that building north of Drake Isles, gotta progress story to get in there behind the sleeping dragon. I just ran into Phantra, its 3rd evolution. I've been running around a bit more than I needed to be, just to fill up this guide as much as possible. This guide should provide overall information about Nexomon Locations, Item Locations, Vaults, Quests, Healer Locations and so on and so on. Finally ran into one, it was in the grass just below the island with 4 bridges coming off it (on the drake isles) Flash 3 years ago 8. This guide will list the Nexomons I found in each field. Others I have no clue where to find them. The developer is tweaking the distribution rate daily, so this should get a lot better over time. A few a know where they are but they just don't show up for me.
