Tips

 * Enemies affected by Acrid's Poison can only be taken to 1hp. Acrid's poison can't kill on its own.
 * This makes items such as rocket launchers, drones, and any other on hits incredibly good.
 * Poisoning the boss or bosses via neurotoxin and epidemic and then running away is a great tactic as it will tick for the same dmg while you're running.
