I wanted to check on these. These skills can be very helpful if they are succesful. I lowered my wit and increased my int and want to know if they are int based. If so an extra 4 int (literally 30% more than normal) would make a signifigant improvement. Please advise.
Int does effect the rate of debuffs landing, but the change from a tattoo would only offer a slight difference at best. Because the way stats work are different for every race and class, a +4 int on a DE Fighter is far from a 30% increase in magic attack. It's something more around the area of a 13% increase. Increasing Int on a mage would actually offer a greater percentage gain despite being a small difference in their total Int number.
in my expierence they land at about 90% with emp/zerk/bsps. It's prolly best to leave tats a lone, or perhaps do a +4 wit to cast them faster. They cast pretty slow as it is.
