First off, a disclaimer and rules question: in previous games there was a general understanding that when first aid (medicae) was applied to a wounded patient, any damage that remained on the patient beyond the healing was considered 'treated' and could only be healed by extended rest/care. However, I don't see that written anywhere in Black Crusade. Is this rule still in effect? For the purposes of the post I'm going to assume it does.
Also, is there a limit to the number of times first aid is applied during a combat? If unhealed wounds after first-aid are 'treated,' the next logical step would be for the doctor to heal as soon as possible, ideally between each hit, so the next hit can be healed separately.
Now, on to my post. There do not seem to be many options for immediate healing. Medicae, via first aid, will only heal one point from heavily or critically wounded patients, and then (if the rule from other games still applies) the rest are considered 'treated wounds' and can only be healed with rest and extended care. Even with Master Chirurgeon, someone brought to -1 critical, for example, would only be healed up to 2 wounds and the rest will require days, or weeks of rest if he is still considered heavily wounded. I understand that this adds to the feel of the setting, but if we are in a pitched assault, for example, and need healing NOW, what other options are there?
In Dark Heresy at least, there were psychic powers that provided healing, but they do not exist in Black Crusade.
Hereteks, at the very least, have Black Blood (autosanguine) and prosanguine. Prosanguine, especially, seems excellent for healing because there appears to be no limit as long as he doesn't roll a 96 or higher on his check.
Hardy seems like a must-buy for everyone, so at least they are always healed for the doctor's intelligence modifier with medicae and heal more quickly with extended rest.
Anything else? Is medicae really as good as it gets for most characters?
