User blog:Burniez/Strategy Zone: Battle 002 Guide (lite)

Afla Dilith's Strategy Zone is easier to beat than Seria's Strategy Zone.-. There are much less things you have to watch out for. With a little bit of the help of RNG you should be able to beat Afla Dilith with no problem. It took me 2 tries to beat him, could be 1st try if I didn't screw up at phase one.

My squad setup: Unit recommendation: For LS, choose units with damage reduction skills. For sub-units MUST bring are Gradual heal, and UBB Angel Idol. Optional but would help a lot are units with burst OD fill. Bring at least 3 mitigators, just in case any of them got that DoT on Phase 2.
 * Ark (Oracle Bangles + Growth Device) LEAD
 * Regil (Eternal Armor + Growth Device) FRIEND 1
 * Regil (Bourn Jewel + Growth Device) FRIEND 2
 * Feng (Prosperous Phoenix Emblem + Invigorating Device) FRIEND 3
 * Elimo (Beiorg's Armor + Health Codex)
 * Stein (Beiorg's Armor + Resistive Device)
 * Felice (Beiorg's Armor + Blessed Charm)
 * Agress (Winter Memoria + Dreadnought Shell Aleph)
 * Melord (Armor of Seals + Bond of Rih'alnase)
 * Zeruiah (Prosperous Phoenix Emblem + Impiety Orb)
 * Fina (Reeze's Armor + Daybreak Moon)
 * Holia (Beiorg's Armor + Curative Device)
 * Elza (Armor of Seals + Courages Aegis)
 * Lauda (Armor of Seals + Mirage Device)
 * Arus (Scarlet Necklace + Infidelity Orb)
 * Ark LS will surely help with the Reduce 20% dmg after 5k damage
 * Regil LS will be able to bring serious toughness to the battle with 60% all stats and reduce 15% damage, and amazing as sub-unit, with high BB dmg and Spark buff
 * Feng LS same like Regil but better since is reduce 20% damage (dmg reduction works on phase 2), and the Angel Idol chance could help if proc (RNG is much needed)
 * Eleanor LS a super defensive one with 100% DEF, 50% HP and Reduce 15% dmg (dmg reduction works on phase 2), tho doesn't help push damage. As sub unit she is mitigator and have reduce 10% from all elements which is amazing.
 * Rozalia LS same like Feng in a way, but help more with BB gauge management with the fill when ATKed and as sub-unit she is like Regil but with some support.
 * Holia's UBB will be needed for her 80% chance of Angel Idol. This will be needed for almost the whole damn battle. Her gradual heal is also important as there lots of powerful DoT.
 * Gabriela completely same reason as Holia, and she help a lot in dealing damage
 * Silvie same as Gabriela and Holia
 * Elimo as mitigator she is always good no explanation needed lol :p
 * Zalts can help with the 8% OD fill, and dealing decent damage while giving BB dmg buff
 * Arus is an amazing damage dealer with the iSBB which means 8% OD fill + 10BC every turn
 * Zeruiah (if you have) all around unit, BC/HC drop rate, reduce 10% dmg, 8% OD fill and iSBB

Guide:

Phase 1 :

Summons Decay God Zurg at 80% Zurg is not a problem (squishy), tho kill him as fast as possible can get a little annoying at times. Zurg will say something and stay idle for that turn, next turn he will do ultimate attack if not cancelled.

Void Casualty: Massive ST and Remove buff (there are patterns like in 6* Afla Dilith trial, but I'm not sure yet) Activate UBB Angel Idol buff before reaching 70% HP, do not BB/SBB too much he is squishy When Afla Dilith's HP reach below 50%, only BB/SBB 3 of your units and 3 units normal attack. Do that until 0% HP of Phase 1.
 * To cancel deal enough damage on him (easy to do since he is squishy)
 * 70% HP
 * 60% HP
 * 50% HP
 * 30% HP

Endless: AoE damage Reduce HP to around 11% - 13% slowly and nuke him to death. At 10% HP he will do Ultimate attack. I nuke through it and didn't experience it, so I don't know how painful it is.
 * 20%
 * Not deadly at all, 50% mitigation is enough

Phase 2 :

You can BB/SBB all units again :) There are not much triggers in here, but a bit of turn counting is needed.

Every 5 turns: ST remove buffs (Whole phase 2) Next turn, cast DoT on the unit that got hit with ST remove buffs (the DoT can take out half of unit's HP). At 50% HP, only BB/SBB 3 units and 3 units normal attack, if not scary things happen.-. Keep doing this until death.
 * Try to maintain UBB Angel Idol buff to most of your units.
 * Recommended to directly swap the unit

At 25% HP it should have trigger some sort of attack, but I survive with normal mitigation.

Reduce HP to around 12% - 15%, then nuke him to death. To be save I use Regil's UBB to nuke him. At 10% HP it should trigger ultimate attack.

I hope that all this will help anyone having trouble beating this Strategy Zone. Note that, I did this with very little guide and all above are based on my experience. So, if anything is wrong I'm sorry.-. also the fact that I can't give specific name for the attacks :'(
