Since there seems to be some confusion about ascended items (and effect on powercreep)
I gathered this info from GT to make it more clear:
Ascended affixes come in 2 types:
(I) Regular (can role on anything and just rolls an extra stat)
(II) Mastery (adds skill modifier, but has 2 very different ‘tiers’ of strength
Examples of regular affixes:
+40 DA (armor)
+25 OA, +25 DA (accessory)
+5% crit dmg (one handed weapon)
+10% crit dmg (two handed weapon)
…
Ascended Mastery affixes
To explain the two ‘tiers’ of ascended mastery affixes, compare all ascended Mastery affixes for UPHEAVAL:
Tier 1 (rolls on MIs, epic and legendary items)
- 5% chance to be used (armor)
- 5% chance to be used (accessory)
- 10% chance to be used (two-handed weapon)
Tier 2 (rolls only on magic items, like ‘Redeemer’ or ‘Preserver’ in late game)
- +3 skillpoints, 5% chance to be used, 10% WD (armor)
- +3 skillpoints, 5% chance to be used, 20% WD (accessory)
- +4 skillpoints, 20% chance to be used, 60% WD (two-handed weapon)
(There doesn’t exist an ascended upheaval affix for one handed weapons)
As you can see you can only roll much weaker affixes on epic and legendary items
For most ascended mastery affixes there is a MUTUAL EXCLUSIVITY in the system, meaning that for most skills if an ascended affix exist in the Tier 2 category,
it doesn’t exist in tier 1 (upheaval is one of the exceptions).
These hellhound bonuses can only be gained in Tier 2 (so only on magic items):
+50 Fire dmg to Hellhound (armor)
+100 Fire dmg to Hellhound (accessory)
+200 Fire dmg to hellhound (weapon)
On the other hand a bonus to Mogdrogen’s Pact can only be gained in Tier 1. Tier 1 seems to have more bonuses to support skills, Tier 2 more to main attack/main pet skills.

How to obtain Ascended Items?
Unlike what was presented in the development blog, Ascended affixes do not drop randomly in the Ascendant campaign. The way to obtain them was changed during development of FOA because it proved too much hassle for the player to filter out all the additional interesting loot.
To obtain Ascended affixes on an item you have to upgrade them at Jornn the Runekeeper:
The initial ascension of the item requires multiple components.
The droprate of the ingredients needed will be better in the Ascendent campaign mode. The pool of Ascended mastery affixes you can roll on the item is dependant on your class. Rare and Epic items will be cheaper to ascend than Legendary items.
After the item is ascended, the ascended affix can be rerolled at any inventor NPC.
Rerolling is cheaper than the initial ascension (or at least for the first few rerolls) and requires ‘Soul echo’s’ which can be crafted into ‘Soul fragments’ at a special blacksmith called the ‘runed orb’
Spoiler about location of runed orb
The orb is in the secret area Elderveil, which can be found to the west of the Guardian’s Sorrow portal.
