Since Cetric is being selfish with his strategy
I'll throw out my experiences and maybe he'll chime in with a thumbs up if I'm in the ballpark of what he's been doing.
It seems the best combo is a melee fighter and a mystic/mage/discorder. Doesn't seem to make a huge difference whether the melee fighter is a Sampire, Wammy or Healing Dexxer. All that matters is they're doing max damage through EoO and Perfection and have a good char set up. The more HP's the melee char has the better. The support char is there to discord, heal and remove curses.
Done it several times with the above mentioned set up, sometimes with 1 support char and a few with 2 support chars. Takes about 10 minutes and usually no one dies.
Now what not to do. As someone else mentioned it appears that the more things hitting her (Players, summons, pets), the more of those 60 point snot balls she sends out. So it's best to only have one thing attacking her with everyone else in a support role. Sorry Tamers, but walking in with 3 Greater Dragons and saying "all kill" is dumb and a death sentence for everyone. Also I don't think a Greater Dragon is going to be the best choice as the thing you want attacking, better off using a melee char. Seen 2 Greater Dragons attacking her and they only had her at half life after 45 minutes, plus both tamers and everyone else around died multiple times. 1 Greater Dragon would probably take 2 hours to kill her. So best to use a melee fighter who is going to out damage the dragon by a mile.
Unless anyone else has seen differently, I believe this is how it works. Part of the reason I posted this is to get the word out to leave your Tamer at home and if you go down there on your no magery char and someone is there tanking it, best to walk out and go get a char with magery and go back and play support. I've played the support role about a dozen times and have gotten looting rights every single time, despite not doing a single point of damage to Cora.
