[MERGED PR] Disarm nerfs the sequel

[palpetinus]

Costing more stamina than dealing seems a tad odd to me - if I want to persistently disarm a person, my chances should slowly increase instead of denying me the option at some point. This feels like disarming would be a bit useless, instead grab an air tank and repeatedly bash the person until horizontal, you'll need to or you'll put yourself in a disadvantageous situation.
