My last post discussed the basics of picking gear in the Loot 2.0 system. It emphasized that a max level character can be geared up rapidly with good rares if you know what to look for and make use of the enchanting system. I want to add a few small points that can make a big difference in how effectively you can use enchanter, especially with limited resources.
A rare item has up to 4 primary affixes and 2 secondary, as discussed before. Each slot has a pool of primary affixes from which it can draw its 4. This is a helpful resource I linked before to see what they are. When you enchant a primary stat, the item can draw the new stat from the usual primary pool (you can click the “?” icon at the enchanter to see all the possibilities in advance). However, the full array of possible affixes is not always available, because certain affixes are mutually exclusive.
In particular, an item can’t have two +skill bonuses or two +element bonuses. So when enchanting a particular stat, if one of the other stats being left on the item is a +skill or +element affix, all of those will be removed from the enchanting pool. This can be used to your advantage when enchanting. Conversely, if an item does not have a +skill or +element affix (except possibly for the one being enchanted), and those are available in the slot, there will be a very long list of possible reforges. This works against you, even if it’s not the +skill or +element that you’re going for. In that situation you might reconsider enchanting the item unless you are willing to spend a large amount of gold and materials rolling the stat you want out of a large pool.
