So..we were actually pretty close to the "Undying" title.. (Which I'm suddenly interested in getting) I thought it was just an acheivement, but it's a title. (No one dies on a boss fight)
So here are my thoughts on getting that done. First, heigen and Kel (His ice block) will be the hardest to deal with for obvious reasons. During those encounters, ppl should boost their health with scrolls, flasks, w/e. During the heigen dance, do not attempt to do anything but move to the safe zones..or cast instants. But cheifly focus on the safe zones.. (Be ready with lay on hands, bubble, stuff like that) and please know exactly where the safe zones are, look it up if you are still unclear. The kel fight: any toon that can heal, should heal the ice'd person. And it's really important everyone is focused and calls out their (Iced) nick fast.
I think this is something we are mature enough to focus on as a goal for fun, without being overly disapointed, upset if we can't pull it off because someone/some ppl make a mistake that cost us the title.
I just think it might be a fun goal..that will inject some new life into an instance we have down.
