Go to the first boss in the forge. Have your whole group go to the ramp that you go down to get to the next boss.
There
are rocks by this ramp...you will fight the first boss by these rocks.
Have your tank and dps face the rocks. Have the rest of the group stand
at the rocks.
Now, your minstrel will heal everyone while the
tank and DPS kill the boss. The boss calls adds, when he does this the
rocks explode. You can run down the ramp when this happens, so have
everyone run down the ramp as fast as possible.
Once your
whole group gets to the spot that you would normally fight the second
boss, you will be able to go straight to fight the last boss without a
timer.
