Or, we could just have 2 levels like I think Snakeblood is (I have never put a point into that so I don't know if it has 2 levels or what) so 2 or 3 Reagents per node.
I think they would be okay if the snakeblood passive reduced the negative effects of other people's poisons on you, and it would have the added effect of making the worst passive in the game viable.
