With the rank 4 CoF bonus, we can now have triple exalts!

Affixes become stronger the higher the level they are. You can craft up to affix-level 5 onto an item.

But Items can drop with affixes that are level 6 or 7. These are called "exalted" and depicted in purple. Usually you get one exalted affix, maybe 2 if you're lucky. The Item in the picture has a level 7 and two level 6 affixes.
