Loot confusion

2 things about loot I don't quite understand.

1st the wiki says all armor pieces can drop on any map (does that apply to rifted?) and that you can target farm specific pieces of rift gear from waves 15 and 25 on specific maps. I see rifted armor pieces dropping on random waves but always the same type. Does the target farming mean that rifted item will be has a chance to drop through out the map but guaranteed on 15 and 25?

2nd Doing rifted massacre mode.  Yesterday was the first time I was able to get past wave 25 on Prom. Started seeing a lot of godly which I ignored because I have rifted trans but I also got a few rifted godly pieces.  Today I finally beat the summit wave 25. I went back to ancient mines set it to ancient dragon bonus wave but never saw a single godly unrifted or rifted armor piece. I made it to wave 33. Not sure how to get rifted godly sets. Prom only gives me 2 types of items for rifted.

Here is what I found when testing things out:

I played Survival on the map, The Deeper Well on Massacre/Rifted until I reached wave 170 and had an idea! What if I started over on wave 99 and put the bonus difficulty on?! I knew I would probably get smashed but I tried anyway. So I started the map over on wave 99 with Massacre/Rifted/Lycan King Difficulty and managed to get to wave 106 before they were just too much!

 

The amount of Godly items dropped were very common, to the point where I was able to be picky. It dropped Godly items of all kinds from accessories to rifted armor.

 

Also, in my search for Arcanist gear, I thought that I could play survival massacre on The Keep without the rifted and hardcore difficulties on and get a lesser helmet. It did not drop ANYTHING rifted (duh), but I did unlock the Lycan King difficulty once I defeated wave 25! Maybe you can try this and tweak it to whatever level you’re playing at. I am going to do the same with the Dune Eater difficulty to see if I even stand a chance. Currently, I can’t win Survival/Massacre/Hardcore/Rifted on The Keep or The Forsaken Temple so I still have grinding to do!
