Power Battle Sukuna Relic & Party Recommendations

The Memory Relic I most frequently use for Power Battle Sukuna is 'Shuryo Tōkōhan' at 5 stars. In high-difficulty content, you need to use Fugue 3-4 times, so the effect of speeding up the Ultimate skill rotation is definitely noticeable. It pairs really well with 'Kansitsu no Mōten/Kaigokudō' Sukuna. Mine is only 3 stars, so I use 'Shuryo Tōkōhan' for now, but if both were 5 stars, I'd recommend 'Kansitsu no Mōten/Kaigoku' for its higher Cursed Technique damage boost, unless you specifically want to speed up the Ultimate rotation. Always match the Memory Relic skill to Fugue. My usual party is Sukuna, Uraume, H-Shoko, and H-Yaga. Uraume's constant effect, which increases all enemies' received damage by 120% for the Cursed Technique attribute, synergizes extremely well with Sukuna. When I want to maximize Fugue's damage during a break, I replace Uraume with Domain Expansion Megumi. Shoko and Yaga are almost fixed, and I only change the last slot depending on the objective.
