iris gold

If you are seriously injured after killing a mob this song will shorten your downtime by healing you over time. It will heal you even faster if you play a string instrument. You can buy iris gold like any other instrument at the bard guild. Kelin's Lucid Lullaby (AE Mezz): You should use it when you are in a new hunting ground and don't know if you can single pull the mobs. You can mezz up to four at once. This can be an advantage when you don't want to train others. The limited aggro range of most mobs gives you the chance to escape fast enough without them following you.
Shauri's Sonorous Clouding (Invis): It is very useful when you want to find out how many mobs are in a camp/room and where they are located. But be careful! Some mobs can see through invis. Always test invisibility from far away at first and get closer when the mob is conning indifferently while having the spell up.
Fufil's Curtailing Chant (Dot): You get this very useful song at level 30. You have to find out for yourself if you prefer the self buff or the dot as 3rd song. When you already have a haste item the dot is recommended because it deals 18-28 damage per tick.
