Make the Obsidian Crown disable all healing

[SgtBriar]

The Obsidian Crown constantly damages you and totally fills up your bloodstream, rendering you immune to every chemical. However, it doesn't disable healing from touch reaction chems like synthflesh. The stun resistance, teleporting away of hostiles and the constant flushing of chemicals from the Crown bearer's system makes them a literal god that you can do nothing to harm. Please make the Crown disable all healing, or change the way it disables chemicals so that poison attacks on the crownbearer are possible.
