iRO calls it Mental Sensing...

[Dandin]

Does this skill:

Prerequisite: Acoustic Rhythm Lv.3.
This Ensemble skill is mastered at Lv.5.
Cast a 9*9 cell area around the casters that increases EXP rewarded to characters and creatures within range. Mental Sensing has an Initial SP Cost of 20 SP and consumes 1 SP every 3 seconds while active.

For bard exist on our server, or was it removed? At level 5 it gives 180% exp gain... that's a pretty large increase.
I'm assuming it's not or else part of leeching services would be planting bards over leech AFK zones spamming that song...

But I thought it would be worth while to ask anyway.

is that Mr. Kim a Rich Man?

It is. Its a duet tho. Also you only gain the extra exp by killing the monsters inside the song radius.

[Guardian Lord]

sooo someone can bring the mob to the leachers and pray he doesn't loose control of it

I used to see this done in niff a while back.  I haven't seen people doing it recently though.
