Barry nailed it. Stand more than two tiles away from her and you will be fine. Also, distance affects the amount of gain in honor, but even many tiles away you will still gain. The difference is very marginal. I generally am 4-6 tiles from her casting ebolts, and gain just fine. My disco tamer does nothing, they go down so fast after disco it's not even funny.
I should have mentioned when I get there I let my cu attack a succubus while I lead the ronin out of the room, down the hall, and around the second corner, into where the fan dancers are located. This will keep him out of your way for the duration, unless he happens to respawn on you. If he does, just repeat the process. The pads allow humans to ride and use Cu's. I have several human tamers, no issues. If you need a Cu tamed on GL, Atl, or LA, I can probably find time to get you one, but you'll want to find the boots first. The Cu's really do rock succubus, because they administer cold/energy damage, which are the succubus' lowest resistances. You can also ride them down there, rather than running with a dragon in tow.
