Yeah, thats a nice item too, I can see why you are sadden by its sudden uselessness
just like im going to feel once my precious Demon sword becomes obsolete...*tear*
Anyways, I think it should be rechargeable, and you get a certain number of charges per hour. Or if Ben or Cory come out saying, that how can poison recharge itself, they can sell like a poison potion? or a poison vile what ever. You can buy it, and use it on the dagger to give it a certain number of charges
and there can be different sizes of viles, and the more expensive(of course) the vile, the more charges it will give to the dagger.
This will eliminate having to buy a new dagger everytime one runs out of poison, and maybe you cant afford a brand new dagger, but you can afford a small vile of poison to give it a few charges.
I think it makes it a little more realistic, that you only have to buy a vile of poison and refill the dagger. Sounds good to me...but then again, im no admin
