Poison Plants, or poison ivy, can be found almost anywhere in Stage 2. If they are walked on, they will turn your Character's color palette green for a short amount of time. Your Stamina will slowly decay and will lead to a net loss of 30 Stamina. This can be very deadly to low-leveled players. It can be cut using a Sharp Knife. In some areas, items can be found underneath the Poison Ivy.
When you are already poisoned and continue walking into more poison ivy, you will lose considerably more Stamina. Walking in the ivy while you are poisoned 3 times will result in you to instantly faint.
