Hello pretty simple, when low on mana/Hp, the bot would use food/water in bag that was looted instead of specifying which food/water to use from Honorbuddy settings.
I know fpsware has been working on this for The One. I don't have his newest source yet so I can't see it, but maybe he'll release it for use as a plugin.
My latest [The One] core library will search your bags and automatically use food/water. EDIT: No reason why it can't be used as a plugin. But overriding the CC's rest (eat / drink) code and using your own water/food could be a problem.
I promised I'd give you healing support for a Rogue. This allows a Rogue to run around and bandage people in need.
