bard instruments
 

Can someone explain to me what the difference is and how you can tell how "good" an instrument is? I can't really find information on this but perhaps I am just missing it? I have seen the class guide listing on the wiki but it basically just says what the entry level and step ups are not what they actually do / modify. Thanks in advance.

merchant weps = "18" modifier = 180% better than song without the instrument.

Some weps are labeled with their modifier value and some are not (dont think classic told us any values). you can test them, but higher level ones are better.

i'd like to know specifically which spell effects are affected by instrument mods. it seems like anything that gives a numerical value (e.g. +STR, +SVM, +DoT damage) is affected.

i don't seem to notice any difference in duration or resistance when playing the fear song using a horn vs. singing, for example. same w/ mez, charm.

Thank you nuggets that is exactly what I was looking for!
