Was just wondering where the high EE items come from, are they found as drops or transmuted or some other way?
Thanks in advance!

I'm honestly wondering the same thing... Lol. People could possibly be making them, finding, or trading for them. My best guess would be finding or using the well.

If you find out lmk!

people used to transmute godly ee items, but the old transmuting method has since been removed.

nowadays, most of the ee finds are through killing monsters in the arena or catacomb, however some people have the ability to transmute decently high tier items.

The highest EE item I have muted with the new system is a 120ee 25 heal I believe.

1.Have the old items been removed or are they still being traded/used?

2. Are the drops from cata/arena based on your level?

1. Old items are not deleted unless by the user.

2. Yes. Items drop 2 tiers below your level. At level 20 the max lvl item you can find is tier V or lvl 10. Check this out http://ladderslasher.d2jsp.org/idx.php?g=14#Metal

Are the chances of high EE increased through something or just random?

it's all random
