Total attack boost from Phoena and Vienta = 1.15 (Phoena's +15% attack) * 1.1 (Vienta's +10% attack) = 1.265, or a 26.5% attack increase. I don't know what to call this; it's not that you multiply the 15% and 10% or something, but you put a 1 in front of those numbers and then multiply them, which actually results in higher numbers than e.g. just adding the 15% and 10%.

People on chainchronicleforum.net like number crunching, and while I don't have any links or numbers on hand, I keep seeing people posting numbers for their buffed units (subparty members, auras, active skills, etc), and they always stack the buffs multiplicatively. And the numbers they get match up with the numbers they see in-game (although sometimes the numbers are off by 1 or 2 because the game likes to truncate numbers and I don't think we quite know exactly where the game likes to truncate numbers).
