1. I wanted to ask about Chemical rule. I play last mission of Sturmdrang Peak campaign. I get item called Weed of Barathias. It replenish my breath while underwater just like breath potion. It's a plant and chemical rule mentions only potions. I can use it infinite number of times, because it isn't spend. It stays in my inventory. So my question is: Is using it will classify my ghost run as chemical or not?
2. Also in the same mission there are purple barriers that I can destroy with sword. They just vanish after single slash. Behind them is only loot and pages for optional objective. Is destroying these barriers a damage property?
