with fort being roughly 45-50% DA rate (will say 50 for this), and having roughly 20% DA from traits, that means you ONLY get a 20% added DA rate on the other 50% of your hits, or 10% on the total hits, so it adds up to 60%. You also get a 20% chance of DAing on the virtue stone DA, but 1/5th of 50% is again 10%. Therefore, you have a 60% chance of DA and a 10% chance of TA. I don't think you can stack these numbers together though (in other words you still have a 40% chance of a single hit...I think...someone correct me if I'm wrong, because the TA is a derivative of the DA%).
