Just thought I would share some of the things I learned the hard way so you don’t have to.
Fallen Embers
They either re-roll an enchant or add a missing one. In my opinion, these have exactly one use - re-rolling negative plagued enchants. Don’t waste them on anything else because you can easily spend upwards of 20 embers just trying to roll the specific plague enchant you want. The clearest way to counter plague enchants is corrupting a common item which has the indestructible facet, and then re-rolling the negative until it becomes unrepairable.
Because this is such a pain in the butt, and the wrong negative enchant can ruin an entire build, the chest piece is really the only plagued gear I run since it has some really good enchants that you can’t get on non-plagued gear. Everything else I use is not plagued since acquiring enough fallen embers for a full plagued set that doesn’t screw you takes ages, not to mention getting a specific piece as indestructible is a pain as well. Crafting it yourself feels like the fallen embers, where you may need to craft 10-20 items just to get the facet you want.
Essence Ember
This is the main way of creating a build since it lets you pull the enchantment off one piece and put it on another. DO NOT waste these on low rolled enchantments. For instance, armor penetration can go up to 15%. Wait to find an item that has an enchant near the max and do not waste precious essence ember on something like 5% armor pen.
Radiant Embers
These allow you to max out an enchantment. This is why you don’t waste essence embers on low rolls. Radiant embers improve an enchant about 10% and since they are just as rare as the others, having to dump 5 or more in to an enchant because it’s a low roll is bad business.
Exalting / Sublime Ember
Limited to four times, this picks a random enchant and buffs it around 40%. VERY powerful. VERY random. Of special importance is that once an item is exalted once, you cannot make changes to what enchantments are on it unless you disenchant it and start all over. Because of this, I recommend building out the item with close to max enchants before exalting. This will give you time to flesh out if it needs any tweaks before getting locked in. You CAN use radiant embers after exalting, so you don’t need to wait until the enchants are fully maxed before exalting. If the enchant you wanted buffed is skipped, you can use void embers to start over. You do not need to find another copy of the item with the same facet you want.
