solo'd some of these at 71drg/whm with no real problem for a pld friend in another room while the rest of my pt fought them elsewhere. for ancient magic i just jumped on them and abused the long casting time while i could >.>
73pld dropped from the pt because he was tired and so did the whm, leaving me and 2 plds who aren't high enough to solo, so i took them to the grid where alot of these popped. got a few links occasionally but there were no more than 2 at a time, spamming tp and dia seemed to help lol, and one of the plds occasionally gave me cure4. but it seems the price for the simple fights was that the key took ages to drop -.-
casted stoneskin and reraise and just started fighting. make sure you have your drachen helm on and a decent amount of mp ;3
