I just press E and one shot enemies in melee attacks. not sure if that was meant, but it gives zero challenge and special attack inta kills an enemy one by one like some giga-chad. too easy.

EDIT : ok, I take it back. it happens only in the very beginning of the game, the INN and the courtyard after it. after beating the first miniboss executions are handled properly and are very satisfying. but again, on some enemies this execttion SEEM to triger just instantly all the time despite there is no shield over them indicating that they are open to it. weird. I think some enemies are flagged to be executed without the neccessity to weaken them first. my guess is this is a bug.
