When farming dracolich you hav ehim(main mob Dracolich) and u have his 7 golem adds that come every 20 seconds or however long.

Making u need a fg to do it.

When farming dracolich u cna glitch the golems so they dont engage on you when your on dracolich.

You can do this with a tank and a cleric, only tough part is killing the adds before engaging the dragon.

What you do is have ur cleric stay in the back while ur tank walks up to dracolich, jus inching his way up in attack mode.
Right when uyou start attacking dracolich stop right there and dont move any closer and no adds will come.
you have to be in front of him otherwise you will get adds.
You can farm him time after time, and draco drops greater power myths and awesome hammer, and of course the necklace.
