Arcanes
Primary Merciless increases primary weapon damage for 4 seconds on a kill and stacks up to 12 times. At max rank it also passively increases reload speed.
It is awarded for defeating Acolytes in The Steel Path, and only kills made with the weapon carrying the arcane count toward the stacks. Status kills count if the weapon applied the status. It works best on fast-firing weapons that never stop killing.
Primary Merciless was added with Update 30.5 (July 2021).
Primary Merciless is tradable, see the current prices in the market box above.
