With crit factored in, Space Gun puts out 73.4 DPS against 55.2 for Diamond Staff — about 33% more damage per second. Base hits are Diamond Staff 23 vs Space Gun 20, so the gap comes as much from attack speed and crit as from raw damage.
Space Gun swings faster at a 17-tick use time versus 26, so it lands on-hit debuffs like ichor, procs set bonuses, and reapplies knockback more often — an edge the flat DPS figure understates.
For crowd control, Diamond Staff hits with more knockback (5.5 vs 0.75), keeping enemies at range while you reposition.
Both are Magic weapons, so the same armor set and class accessories buff either one — you can swap between them without rebuilding your loadout.
