Can be soloed by lev 60 with no death at all.

Enter instance and take left path, not left stair.
when u reach place where is one ladder up to left, and one down to right wait for patrol to pass down, and go up, now u at upper ring, u need to take right turn and go huging inner wall to avoid mobs, then u reach another passage leading ladder down, it will be to right of u on the outer wall. Take it and after u gone one ladder down go left to a green-casting dude, there u jump down (carefully, not aggro mobs) and now u need to get inside north-east dead-end. It's said there is mobs guarding, but u can avoid them, for that find a column between north and north-east path, behind it will be some stone rune, if u jump on it u can jump on wall edge, and following it u can pass by those mobs without aggro, and all left is to get farmost edge of mobs near elder and take coin, u will not get aggro. To get away jump slope at north part of tunnel, and follow edge of wall like u done before, go to north tunnel, and now u need to run, u will walk down circular ladder and escape trough instance entrace. =DDD
