So I beat Trial 01 and Trial 02 in Trial of the Gods (new vortex) in 1 try each, with no gems, after a shitload of reading about what strats people are using on reddit, and applied it to the units I have leveled, here's how it turned out.
Trial 01:
Team:
6* Bordebegia leader (Mystic Lantern, only SB1) - Used him just for Ares' Excelsior buff.
6* Michele (Sacred Jewel, SBB10) - Atk increase
5* Zephyr (Medulla Geml, SB1) - Leveled him as high as I could from 4* lvl 1 at the last minute, just for Ignore Defense.
6* Zellha (Sacred Jewel, SBB6) - Big AOE 30 hit damage with high chance of Injury/Weak
6* Melchio (Sacred Jewel, SBB10) - Status NULL protection.
6* Luther -Friend- (Can't remember what Sphere, SBB10) - Spark dmg and more BC gen.
Items brought: Holy Flute, 2 Fujin, Cures, Divine Lights, 2 Revives.
On the first fight I popped a Fujin on Zephyr for ignore defense buff, and attacked all in.. got Melchio's SBB in on 2nd or 3rd round in time for him to do his AOE Paralyze, so I didnt get any of my units stunned.. went down pretty fast.
Second fight I had all my units ready for SB/SBB, used Zephyr first for Ignore Defense, and 1 shot him.
3rd fight same thing with almost all SB/SBB ready, Zephyr's ignore defense made the grass boss die in the first volley, 2nd round the water slime died, then took a few rounds to take out King burny.
Trial 02:
Team:
5* Hatsune Miku (Medulla Gem, SB2) - Huge BC gen.
6* Lilith (Divine Stone, SBB8) - She is part of my attack plan to kill last boss before he heals.
6* Melchio (Sacred Jewel, SBB10) - Status NULL/Protection
6* Michele (Sacred Jewel, SBB10) - Atk up.
5* Themis (Sacred Jewel, SB1) - My only premium healer :/
6* Dilma -Friend- (Drevas, SBB10) - His Dilma was breaker for 3000+ atk, lol, used to do huge damage to last boss and also as ignore defense. Honestly, the only reason I beat this place in one try.
First fight with Weiss I guard every 3 turns with all my units. When it's time to do massive damage I use all BB's except Themis, and heal with her after, cuase all my guys will be almost dead becuase of reflect. Slow and steady fight but got it done.
Second fight Dilmas ignore defense along with all the other BB's killed Mifune on first turn, then it was a race to get Luna down as fast as possible, she killed 2 of my units with huge attacks, had to use my revives and alot of heal pots before she died.
Third fight, Juggernaught will FULL HEAL himself after 10 rounds, so you must kill him before that happens. Luckily he does not do a whole lot of damage per round, but things got scary because my healer died fairly early and I had no way of reviving, and I was pretty low on cures/lights. Lilith and Dilma took him down by round 7 or 8 though.
Gonna try trial 3 tomorrow, good luck everyone, the sphere at the end of most definitely worth trying for.
