Damage 1.0/Poison Damage

Poison damage is actually extremely similar to the Physics Impact damage type. It is almost always (currently) included in the enemy list of damage types to not apply armor to, and it has no damage type multipliers to do a flat bonus or reduction to it.

In generally, this damage type is used more for themed damages rather than an actual balancing aspect. Because of its similarity to Physics Impact, there really isn't anything special about it besides its theme.
