skilled up quite a bit in sea casting threnodies on goldfish.
So it still works? ;/
is there cap on them?
According to the wiki, the higher level goldfish (Om'hpemde) range from 73-77 (the lower level ones are 68-72).
As of about a year ago,
you can cap skills on DC mobs. From the wiki's Experience Points page, that should correspond to mobs 1-7 levels below you (at least for the relevant range). The highest level goldfish should be able to get your C rank singing/etc skills to what they'd be for 84 (274).
If you happened to pull a level 68 Ul'hpemde, then it would only skill you to 75.
