yay another person that can play the game with skill!
1 tia or knight with an endurance pot will kill cini, no problem. a voke chain+ meat shielding works too on both cini and lir, as well as the dodge when they stop method.
as for lir herself, pretty much, make sure that you can see what she's doing at all times, and try not to move too far away whenever she is attacking, a couple of her attacks are seeking, so it's best to stay close to her rather than distant.
other than that, it's very, very easy.
if you have a good party, it'll translate to 7 to 9 minute runs, very easily, (faster than almost all trapping parties, since you dont waste time trapping, and you dont have horrible players that are high level, but dont even know how to kill zakan without trapping, LOL. but i digress)
if you catch one of my parties in list, you're welcome to join ^^ or we can duo it xD
