She has focus skill and high morale generator to replace both 2B and FA.Rain are possible but their morale gen. are lower than Aya. Hopefully you can reach 175% morale gauge on Turn 2. For FA.Rain, Focus T3, Shift LB T4 for sword imperil and Triple Pulverizing Force T5. Give him another Wylk VC. If you only have one, Melissa will use her own VC. For 2B, she had to use Focus skill T3, Shift form LB T4 and LB T5 so you need to gear her with LB fill rate and LB fill per turn and change Chow T3 action from Netherworld Stream to Fluffy Watchdog, the rest is the same and T4 use beast killer, 2xBarwaterja, 150% water amp. (after 2B Shift LB) and Melissa can change her Enchanted Dial - Dragon on T4 and T5 to Bardarkja too (Ang has 250% AoE Dragon killer in CoW).
