Krantz Lead

Elza

Reud

Avani

Griff/Avant

Gazia Friend/ DPS Friend with HP Boost (Avant/Chrome)/ BC Support (Haile, Bestie)

Krantz is for the sweet 30% HP and 100% Attack, + the Light and Dark Element Buff and mitigate + Heal. Trust me, he works wonders for this trial. The subs are there to fill Krantz's LS requirement (5 different elements) which is totally worth it. You can replace Avani with Elimo so you have 2 mitigators (which might be really helpful since Gazia has BC resistance, and Elimo doesnt attack so you're safe from Gazia's Damage Reflect on his Call to Exile Stages). You'll still have Elza for your damage output, and Griff/Avant is also there.

Don't replace Reud, however. In this trial, it is very important to have A HEALER OF BOTH KINDS (in your case, Reud and Krantz). However, Reud's HoT is only in his BB so you have to switch to using his BB every 3 turns. He provides a very good spark blanket and an excellent BB fill rate boost, so there's that.

You might also consider getting a Tridon Friend, since his UBB can survive Gazia's Ultimate at 20% HP second form, Holocaust (leaves all your units at 1 HP). This is where HoT becomes necessary, since he'll keep spamming Talon of Pain which inflicts Heavy DoT and without HoT, can wipe your team.

Attacks to watch out for:

Dispersal Field - 80% Damage reduction for 3 turns. Make sure to heal every turn and to nuke 10% HP from him as fast as possible. If you don't kill him within 3 turns after he casted Dispersal Field, he will cast Ruination and the game is over. You're safe if he uses Talon of Pain. Use Reud's HoT afterwards.

Call to Exile - Damage reflect. High damaging units will get damaged back and will be left at 1 HP. Attack order will be: Everyone else -> Reud HoT -> Krantz/Elimo Heal (make sure to have your healer last, or else your heals wont count because they will get their damage reflected, in which case Elimo is wonderful as she can't get damage reflected)

Holocaust - Use 75% MItigation UBB (Krantz, Elimo) or try to nuke him (Avant UBB). By the time he reaches 20% though, which is the requirement to bypass his last Dispersal Field, he'll still have 80% Damage reduction so nuking him might not be good if you don't have optimal spheres. You can also find a Magress/Nadore/Will Friend for 100% mitigation (you get only 1 damage) to nullify his ultimate attack.

Items:

2 Dews (You can use Angel Idols if you dont have any)

2 Revive Lights

1 Revive or 1 Hero Crystal

5 Fujins

Good luck!
