On prismatic hammer strike is outclassed by literally any other option in terms of risk/reward. The closest comparison is shiver strike which does more damage, and freezes/slows without needing a kill. Arc = thunderclap or dive if youre feeling frisky. Shouldercharge isnt a consideration. Void = this one might be ok ngl in very specific builds/scenarios but still just not enough damage to warrant the risk compared to the guaranteed overshield free to use melee. Since these melees are the only ones requiring a sprint startup + put you in a risky spot they should atleast do the most dmg.
