Loving the compedium series idea theres so many personas in the game its very hard to grasp who is worth investing into and how Much thanks for the guide!
The famous Revolution + Rebellion combo for any boss. Dionysus and Koumokuten are used differently because of passives. You bring out Koumokuten on turn 1 for attack buff. Dionysus is more like swapping in mid battle and doing crit buffs plus his crit damage boost. In guild boss you apply rebellion/revolution to dps 2 turns ahead of weakened state, then apply the other one using Dionysus. For example: Turn 1: Wonder, Koumokuten uses rebellion on Joker (boost Joker's attack and crit rate entering battle) Turn 2: Wonder, Janosik uses tarukaja/rakunda on boss (Joker proceeds to kill the boss) Weakened 1: Wonder, Dionysus uses revolution on Joker (Boost Joker's crit rate and crit damage. Stack with Rebellion) Weakened 2: Wonder, any persona uses buff on Joker (Rebellion + revolution still effective. Wonder can attack or use buff) However, using both revolution + rebellion means you lose the chance to apply other buffs/debuff, so to maximize score people may choose to use rebellion only then roll more for RNG. On Dionysus or Koumokuten I would recommend "Apt pupil" series to the skill list. They are passive skills to buff Wonder's crit rate. You can learn Apt Pupil I from Bicorn, or Apt Pupil II from Kin-ki for example. Then you make Wonder's crit rate a multiple of 10 in battle. For example, I bring Phoebe in battle and she has a crit of 25%. She shares 20% stats so my Wonder has additional 5% crit. Then my persona has Apt Pupil II so Wonder has 5% more crit rate, which makes Wonder's crit rate to 30%. When I use rebellion, the dps would have 4.8% more crit (1.6% *3). Something like that.
