While I was killing rares in Silverpine Forest I noticed that the greens they are dropping always have the same level requirement. After leveling a few characters I noticed that there was some sort of pattern to how gear scales and learned how to get lower level BoE drops to scale up to a higher level requirement. Now, if you've got a level 10 twink for example, every drop is going to scale down to a lower level than 10; however, if you're level 13 every green that has dropped so far has a level 10 requirement and better stats than the gear you would have looted at level 10. After seeing this, I began trying to find that sweet spot for 19 or 20, but no luck......everything goes from a level 16 requirement before level 25 and straight into a level 21 requirement when you loot the item at level 25. In other words, if you have a 10 twink, you are no longer bis unless you have a 13 twink to give gear to the 10....the same could be true for 29s 39s etc but I'm not sure yet as I haven't tested it and don't know what level you'll have to be to get gear to scale up. This kind of BoE scaling does not seem to apply to dungeon drops as far as I can tell. I don't know if it will apply to blues like magician's mantle, feet of the lynx etc. I don't know if this scaling applies to chest farming, but I'm anxious to find out. If anyone's leveling a character that's barely above 29/39/49 etc, I invite you to post any findings here.
