Faith and arms!
May Lord Vaizel guide your footsteps.
Listen...do you smell something? It's dried Moonflower roots!
You don't like the smell? Heh. It's understandable that poison has a bad reputation. Most people don't understand the good it can do.
Taken in very small doses, many poisons have a medicinal effect. If you know what you're doing, you can administer poison as a purgative, driving out even worse contamination from the body.
Our Seraphim Lord of Liberty, Vaizel, never forbade us from studying or using poison. Significant, don't you think?
