I'm rolling the attacks without some of the bonuses because I'm still confused about which ones are still active. But bellow is the list of the ones I found. Please add the ones that are still up, but I've already added the Aerial Combat Training and the +2 from Janis' plan.
Bonuses: +2 from Janis' plan, +4 from Aerial Combat Training, +2 from Star, +5 from Ror's CoGH;
Base: +24/+24/+19/+19/+14/+14/+9
Base with the Aerial Combat Training and Janis' plan: +30/+30/+30/+25/+25/+25/+20;
Damage: 6d6+18 (Flaming Aura +1d6, Elemental Weapon +2d6, Searing Blade +2d6+11)
