Memory of Chaos Stage 12 Best Teams

Use Ice and Lightning Units in the First Half

Enemies in the first half are weak to Ice and Lightning. We recommend using units that can deal AoE damage easily defeat the Flame Reaver's clones.

Use Physical Units in the Second Half

Enemies in the second half are weak to Physical. We recommend using units that can apply Shields to your team since it'll make fighting the Sweet Gorilla and the Judge of Oblivion easier.

How to Beat Stage 12 - Category Mistake

Category Mistake First Half

Defeat the Furiae Praetor First

Star Rail - Memory of Chaos Stage 12 - Defeat the Furiae Praetor First

For the first half, focus on the Furiae Praetor first since it can summon enemies and absorb its summons to deal massive damage if they're not taken care of. Once it is defeated, you can easily take out The Ascended next.

Defeat The Flame Reaver's Clones

Star Rail - Memory of Chaos Stage 12 - Defeat The Flame Reaver

The Flame Reaver summons clones of itself that deal a lot of AoE damage if left unchecked, so focus on taking them out. Defeating them damages the Flame Reaver and also prevents it from using its final attack that deals massive damage.

Category Mistake Second Half

Bring Shields To Counter Sweet Gorilla

Star Rail - Memory of Chaos Stage 12 - Bring Shields To Counter Sweet Gorilla

For the second half, having a character that can apply Shields to your party is key to defeating the Sweet Gorilla and Judge of Oblivion easily. Having Shields reflects the Sweet Gorilla's attacks to itself.

Use Shields Against Judge of Oblivion's Attacks

Star Rail - Memory of Chaos Stage 12 - Use Shields Against Judge of Oblivion

The Judge of Oblivion's Hemotort Teethgrind attack inflicts massive single target damage, but if the character has a Shield it reduces the Judge's Toughness instead. This makes it easy to reduce its multiple Toughness gauges and inflict Weakness Break on it.

I don't know if this helps anyone but I finally this in under 10 turns using Hysilens/Kafka/Ruan Mei/Gallagher against Svarog. If you have Robin, you can switch her instead of Ruan Mei. For Aventurine, I did the standard Hyacine/Castorice/Tribbie/RTB. Tribbie had been using an S1 DDD! but I traded it out for an S5 Cogs. Way more Ults for Tribbie. Brute force, rely on Mem's True DMG and Action Advance and make sure to spend all of Pollux the turn before the Mad Party so you don't breath dice.

Clearly dev have never playtested V3.3 MOC12 while MOC11 is super ez. Not only Hoolay has so many consecutive moves, he also has a lot of HP. At this rate I think even until 2030 they won't reduce MOC12 boss' overly-inflated HP, not even worth playing. For those haven't tried, just go until MOC11 srsly
