“Ada-1 will be offering 20 free focused Exotic armors per account to anyone who has Tower access prior to the release of The Edge of Fate” (TWID 6/26). I’m going to assume those focused exotic armor drops will be weak tier level compared getting exotic armor as RNG drops. “Exotic class items: they are the only armor from before The Edge of Fate that will be converted fully into the new system. Each one will receive the maximum stats available for an Exotic (30 in the primary stat, 20 in the secondary stat, and 13 in the tertiary stat)” (TWID 6/26). Seems like the strongest build with a piece of exotic armor to begin Edge of Fate will be Prismatic and Exotic Class Item.
