Did this 3 minutes ago as SMN75/WHM37. 1/2 on it. Couldn't find any SMN solo guides on any sites so I went in assuming I'd be kiting as usual. Went in RR'd buffed carby'd and went it. Put carby on the Khimaira 13 and just kited up and down the ramp. about 2 minutes into the fight he annihilated carby and came after me. after I died he turned on Karababa. I got up and saw that she took the thing down about 50% by the time i had gotten back up. I didn't cure her fast enough so she escaped leaving me with carbuncle and Doom.
Second fight i did the exact same thing but was very careful to run as fast as i could to the other end of the ramp and cure or buff SS OR Blink only once per cast of carby because he rips through squirrels like nothing. got him down to about 75% then I took a dive and released carby. Summoned Garuda, and Predator Clawed him. took him down about 7% and then desummoned. and waited for Him to rip off my face. He did, turned on Karababa and I popped up. Started to cure bomb the hell out of her. if she got below 70% I used my one Divine Seal to bring her up. Thue just kept rotating Cure II and Cure III till he got a lucky shot on her and brought her to 48% and she escaped.
When Karababa runs I didn't have hate, so I summoned Fenrir and Eclipse bit the last 3% away.
No food or Yags used. I had an Apollo's Staff, Yinyang Robe, and an Evokers ring to keep my MP capped before I ate it.
