In 4 years of playing DDO, I never ran Reaver's Fate. I got interested in it few days ago, mainly in order to get Dreamspitter for my new Acrobat. I have a level 21 bard/ranger, so I figured I may be able to solo a level 14 raid. I practiced the puzzle and watched this solo run. Seemed straightforward enough -- wear down Stormreaver while he lights up the orbs, then kill him, fly to the ceiling and throw the spike-covered tunnel, turn the lever, fly back out, fly to the puzzle, solve puzzle.
Reality proved to be harder.
My first attempt seemed smooth enough at first. Couple times got dangerously low on HP when hitting the ceiling, but I killed Stormreaver. Flew to the lever, then apparently took a wrong turn on the way back and ended up in an oubliette of sorts. Then found that my Fly spell apparently has run out. Cannot jump up to the entrance into that miserable pit -- nothing to do but exit. Well, at least I did not die.
Talked to my guildmates, and one FvS 22 agreed to help me. We beat down on Stormreaver, when suddenly my friend hits the ceiling spikes and dies. A minute or so later I hit the ceiling, lose half my HP, try to heal. Not fast enough -- also dead.
Third attempt. Now there are six of us, levels range from 16 to 22. I am first one to die. This time having no reason to recall right away, I take stock of my surroundings and realize I am right near the lever. Two more people die and pop in next to me before Stormreaver is dead. Party member flies up the tunnel, finds us, collects the stones, pulls the lever. Suddenly all three of us are down on the main floor, still dead. "You are out of range of your soulstone." Before anyone can figure out what to do, we rubberband back to the lever room.
Few more tries show that every time lever is pulled, all dead people go to the floor for 10 seconds. So the guy on the lever pulls it yet again, FvS sends me a Raise Dead. I click "Accept", find myself alive... a second later I am dead again. Wha...? ...then I see that everyone is dead. We ran out of time and Stormreaver's doomsday device went off.
So, what is the proper strategy? Also, are lever and/or puzzle accessible while Stormreaver is still alive? Is it possible for one person to fly to the lever and for another to the puzzle before Stormreaver is dead or before the orbs are lit?
