Almost ANY green person will heal you - Gordon Greer being a really good example. The trick is, if you are at full health already, they say "I've got nothing for you." They will only talk to you and give you healing if you are not at full health. 5gp for full healing is cheaper than tonics - and can be repeated a dozen times DURING your fight with that level 35 assassin.

A demonstration. On Outcast, there are two new NPCs. I got let a stump thwack me for a while then finish it off, then run to Dog Lockgrim. Note that my health in the top left corner is all the way red. I then talk to him and I'm instantly all better. But once I do, I can't talk to him anymore.

yeah this is prob the best way to lvl up dagger altho if you are a lower notority lvl (say 20 to 30) you can always incorp. hack and slash into your combo so you dont slaughter your enemy in a few hits but its still quicker this is the way i have always done it at least on my lower lvl pirate

I have never leveled dagger with just throw. Its just to easy to level it while leveling three or two other things. With the bosses, this can gain alot of rep even with using the bosses with the healers. I still get 250 rep on one of the lowest level bosses so have been doing that rather than using the healers. Though not using upgraded weapons has alot to do with it.

Apparently the Throw Dagger loads Slower so this Technique doesn't work as well.

It used to be alot faster, till they added in the new abilities for it. However, those points actually make it viable for at least one point, so yeah.
