I'd like to avoid killing the tree as much as possible, but it's not like I have much in the way of ideas at the moment, myself.

[ At least, not right now, anyway. ]

But I'd like to at least put it out there that the shit that's been showing up? You know, the goo? Yeah, I took a look at it under a microscope. It's fucking blood. Magical blood, but still blood.

If it's coming out of the tree, I'd say that "putting a bandage on it" would be the best idea, hypothetically, but I have absolutely zero supernatural healing abilities.
