Tales of the Valiant Players Guide (pg. 131)
Prerequisite: INT 13 or Higher or Proficiency with Herbalism Tools
You invested countless hours in the art of poison crafting. You gain these benefits:
• Double your PB when using herbalism tools to harvest a poison.
• When you harvest poison from a natural source, such as a creature or plant, you harvest twice as much.
• When you apply poison to weapons and ammunition, it lasts 1 hour instead of 1 minute.
With one hour of work, you can concentrate, customize, or otherwise empower a single dose of poison. When you do, that poison gains these benefits:
• The poison ignores resistance to poison damage.
• The poison’s save DC and damage both increase by an amount equal to your PB.
• A creature that fails its save against your poison by 5 is poisoned until the end of its next turn (see Appendix A: Conditions).
