Hello there. I played in a server that provided a buff called cozy mucus . the picture has a gold-green frog and the buff is for archers.... i wonder, is there actually a class that has this skill in L2 freya, or was it just a server custom? thx a lot for any help provided

What the fuck

LOL i found it guys. you better all try it in the servers you play. it is a curse like cholera, malaria etc that we take from hotsprings.
But this one you take it from the plains of the lizardmen from a mob called rainbow frog. It significantly increases archers p att. The duration varies from server to server. I found 2 servers where it lasts 10 min, one that lasts 20 but unfortunatelly in more than 10 the duration is just a min . So, run to the plains archer boys and girls and check out what happens in your server Best of luck...
