Once that percentage is added, the damage is rounded “normally” – that is, up if the fraction is .5 or higher, rounded down otherwise. So a Flirt attack that was randomly determined to do 8 damage would do 15 damage at Offense level 12. (8 + (8*.85)) = (8 + 6.8) = 14.8 rounded up to 15.

In the research some of the flamers have done it’s been indicating that it’s floored, not rounded. Not sure tbh.
