we pulled this guy when we had like 1min left..blms 2hrd and owned this thing in literally 30 seconds..finally beat this peice of **** dynamis on the 3rd attempt..it is by far the toughest of the main cities, requires 35+ ppl with lots of cooperation and paying close attention.
in order of difficulty: windurst>bastok>jeuno>san'doria
When its casted on you, you have to 10 seconds to use holy water or something similar to that. It will remove the countdown. If you die from doom, you cannot be raised, not through reraise, not through anything. You will have to hp and re-enter dynamis
Sounds like they brought back the Old Blue Magic "Countdown" Countdown does this Inflicts a Timer on Target Ranging for 10-30 secs. This Means Unless you Have Reraise (Or Something Similar) or a 25 WHM/38 RDM/75 PLD, YOUR DEAD when time Runs out. When Time runs out the Actual Spell takes place-Death/Doom. Now I haven't Been to Dynamis and from the Looks of it...I'll Never go in there unless the Upgrade some Spells for the RDM (And bring out the Ultima Spell :])
