Ixion's difficulty is laughable comparing to other advents. For example Ilyanka ragnarok had overdrive 8 or 9 hits 1.8k each (-40 attack), Ixion - 3.2k 1 hit (-50% attack, elemental advantage), and so on. On ultimate my team of Mordred (trial), Hastur, Iblis, Maeve, Itaqua kills boss on turn 0 (just active skills is enough) On rognarok i change Itaqua to Sol aw just in case and if hearts procs - boss even may not overdrive (on ultimate with Sol boss has less then 5% after skills and 1 turn is needed). Easiest advent ever. Too bad that there is no FLB to sword and bow is another garbage rush/defenrder like Illyanka gun... or not to bad because i can grind less - just books, jevels and tickets, and last but not the least, garbage eydo for orbs.
