Relatively pointless question, I know, but just for the sake of trivia is the increased slow effect for Tclap from having multiple pieces of the Conqueror's Battlegera set additive or multiplicative? The text says "Increases the slow effect of your Tclap ability by 50%". So if Improved Tclap is already 20% Slow, then does this bring it to 30% or 70%?
