Medicine
In the inventory, you need to choose a Powerful health treatment. This remedy will gradually remove the poison from the body. You can buy it in a store or make it yourself. To do this, Arthur will need ginseng.
As soon as the medicine is taken, a text will appear in the corner of the screen. If that didn't happen, Morgan would have to go to sleep.
Complete healing
If there is no medicine or ingredients for it, treatment can be continued with the available funds. You just need to fill up the health bar and go to bed. Over time, the poison will stop working.
