Archetype Enhancements
Overview
Archetype Specific Enhancements (Also called ATEs or ATOs) are sets of all-Unique and Attuned enhancements, one set per archetype (Kheldians and Soldiers of Arachnos both having one set for both archetypes). Each set contains a proc or global tailored to that AT's role (Stalkers have a placate, Kheldian's a changing bonus based on current form).
Availability
Originally to be made availalbe in SuperPacks only, feedback has made it so the developers will also offer these enhancements via reward merits and astral merits in game.
Superior Enhancements
While the standard archetype specific enhancements are attuned but not Account Bound, in SuperPacks and from incarnate trials there are Enhancement Catalysts which will make the standard enhancements into account bound versions with higher enhancement values. They will be for level 50s only.
