Garrote:  Learning includes "show_gloves_combat" attribute.  Checks pinning and silence immunity as appropriate.  Will not waste cooldown on dead targets.  Cooldown starts even if the status effect fails to land.  EFF_GARROTE_SILENCED removed, silence effects folded into EFF_GARROTE, tooltip/description corrected.  Unarmed attack correctly auto-hits and bypasses evasion.
