How to unlock the Decimation achievement in Path of Exile - Definitive Guide
On top of this, I used the same map that I got the "corrupt a map to have 8 mods" achievement. It was brutal and I died 5 times, but using that map I knew for sure there was 8 mods plus the two sextants.
One thing thats worth mentioning though, just because there are items listed when you bring up the full map, that doesn't mean its a mod. For instance, the top entry in the current league says that Harbingers can appear, this doesn't count as a mod. Similarly, one mod can add multiple lines to that screen, like "increased monster attack speed" and "increased monster cast speed". This is only counts as one mod. There are others like this too, that was why I chose to use the same map that I got the corrupt-8 achievement with.
If you're concerned, you can always search this page with the mods you have to see if any multiples are only counting as one:

1. at the time of publish this guide the atlas works whit watch stones and the maps are divided in regions so to you need to get four stones that is Green, Red, Yellow and blue this are dropped after you defeat every one of the sub bosses drox, veritania, al- hezmin and baran.
2. - after you get the four watch stones buy a red map from zana in my case was spider lair is a red map level 14 situated on the region Glennarch Cairns, when you buy your map make sure it has mods that your character can run, and counted for this les make the assumption that this map has 7 mods added to it
3.- aplay 1 sextan on every watch stone that you have in the region you put them on again check that every mod has been added to your region is a mod you can run in my case i put 4 journey man sextants, this will give you 4 more modifiers on every map of your region.
4.- add 2 scarab on your map device and one fragment of atziri and your map this will give you 3 more mods on your map
5.- before you open your map select one more mod depending which ones are active on that league could be Harbinger, Abyss, beyond...etc. this will give you one more mod.
in total depending on the number of mods on your map will give you aprox 15+ mods then just kills the boss on the map and the achievement will pop up
i hope this help you for more info i will leave a few links here
PD: if you need help feel free to send me a msg on xbox and maybe i can help you.

This trophy would be best obtained with the corrupted 8 mod map trophy, Hostile Territory. In addition to the 8 mods on the corrupted map, you will also have to use Cartographer’s Sextants on either the corrupted map location or on maps that are close enough to be within the radius of the sextant mods. Some maps are more suited for this than others, as Sextants work on a fixed pixel radius and not all map nodes are equidistant from each other. There is a limit on the number of sextants that can be active at the same time. This limit starts at 1 and is increased by 1 when you complete the bonus objective on all White/Yellow/Red maps and also when you complete all Zana's quests, to a limit of 5.
