Once you have entered the new map, take the stairs to your left up into the next map north and this the location for this drake. Walk around the lake heading west then south. Tribute of Ocean Glamond For this drake from the Frozen Tundra warp head south into the next map then south onto the map with the cave to the right. If you follow the southern route you will come across green grassland with a mound in the middle and that is where this drake is located.
Tribute of Thunder Volta This drake can be found in Palmaya. Tribute of Mind Mystogen From the teleporter in the Immortal Citadel head west into the next map then head north and you will immediately be at your destination. She will be standing under the tree to the right. Once in the next map head west to the map with a big skeleton, head west from the skull and follow the grass around to the golden chest. From the teleporter head north into the next map then proceed to the north again. Tribute of Blaze Dracon This drake is located north of Ignitia. Tribute of Decay Krainnull This drake can be found from the teleporter of the Immortal Citadel going all the way east until the end where the giant skull is located. Loop round and head north through the entrance you saw, keep heading north until you reach the abandoned mansion at the end of the path. From the Outlands teleport keep traveling south until you reach the abandoned town, exit through the south then immediately to your right there's an entrance. Tribute of Power Wyverne This drake is located south of Outlands. Information gathered from the Nexomon official discord so all thanks to those guys. You need all Tribute items obtained from the vaults. This is end game content and cannot be completed before completion of the story. Enjoy the story first, that is the best part of this amazing game, and collect them all later if you want to.Here is the location for each greater Drake. 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: 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 hope this guide will be useful and that you'll find the Nexomon that you're missing. 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.
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. 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 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.
