Verified answer
What are the first Primary Aberrant choices?
Quick answer
The opening choice shown in the official hands-on is Flurry, Slash, or Slice. Flurry uses fast twin daggers and boosts critical chance; Slash is a wide scythe for groups; Slice is a high single-target axe with bonus damage from behind.
What this means
These are distinct Primary Forms, not interchangeable names for the same weapon. Other forms can be unlocked later, but the opening choice introduces mutually exclusive specialization early.
