I made this, so I'll put it here.
PROTIP: If you're Dual Weilding different weapons with Orlandeau put Excalibur in the LEFT hand. That way it will be used for the second swing of Divine Ruination, allowing it to benefit more from the light debuff and give you a bit more damage.
PROTIP: Marie is one of the best supports in the game, but has no healing spells innately. However, if you equip her with a Healing Staff or the Carbuncle Esper she can get Cura! With her innate Dual-Cast she is a useful backup healer.
PROTIP: Chaining is a great way to blow up some bosses super hard. For two Orlandeaus, the key is to input the Divine Ruinations nearly simultaneously. They will not chain if you Cue + Toggle Auto or by using Repeat. You must manually enter them nearly simultaneously. If you do it just right they will chain to 28. Issue an Olive True Shot right before and you can one-shot even ELT Ifrit! (with the right preparation)
PROTIP: Done with the Ifrit Raid after getting your Trust Moogle? Don't stop farming it! Not only do you aid the rest of the community, but you'll also earn tons and tons of Ifrit Raid coins from clearing PRO and ELT. They sell for 50 gil each! That's 90k gil per run of ELT! I've made 8 Million gil in the last week!
PROTIP: Don't buy the 1% Moogles from the King Mog event! Each one costs 10k Red Stones. Running Elit it would take you over 100 NRG on average to have that many Red Stones. However, if you run Earth Sthrine you can get 0.2% TMR on 5 party members in an average of 20 runs, which is only 20 NRG! That means these moogles cost FIVE TIMES the NRG for the same amount of TMR! Not worth.
PROTIP: What's better for an accessory? +30 ATK or +15% ATK? The break even point is if the unit has 200 base attack. Above 200 base attack take the +15% ATK. No unit in the game has 200 base attack yet (as far as I'm aware), not even Olive or Orlandeau with full Attack pots. Additionally, Doublehand takes into account equipment ATK, making the flat ATK even better for Olive!
