well, there's actually two possible confuse effects in RO.
the first is that phsycadellic lag fest that makes you need to relog if you get it. Which is probably why it's deactivated.
The other one is confusing damage numbers. I.E. way way too high to be realistic like a series of 1200s coming from a hyrozoist. Or way way too low to be realistic like a series of 100s from a Rori Ruri. This is the probably the one we're using here.
