I'd like to know the viability of this and if it would be balanced or not.
We've seen a lot of weapons in the game which have a medical aspect to them, which are hardly ever used (Cautery Sword and Wrench Wand). What if the charge attack of both of these, instead of healing an ally, gave them 1 pip of your health?
I'm just wondering because people have been asking for healing weapons for a long time, and I'd like to know if they could be implemented into the game.
...go search through the forums for healing threads yourself. That should give you all the answers you need.
There have been good, bad, and ugly ideas.
