Reverse 1999: The Best Regulus Build (Psychubes & Team Comp)

screenrant.com:

Regulus is a unique main DPS inwho alternates between periods of rest and action. With Insight One, when Regulus spends a round inactive, she gets a status called Restless Heart. Restless Heart boosts Regulus's Crit Rate by 50% and converts the excess Crit Rate into Crit DMG. This fuels her Incantation, Challenge For The Eyes, which steals Moxie from enemies at two or more stars.

Regulus is a Star Arcanist who deals Mental DMG. Her build revolves around Restless Heart and its ability to deal consistent critical hits. Because she needs to spend every other round inactive, she needs a team with strong secondary DPS characters. She also needs a Psychube that can take advantage of her unique critical skills.

Since Regulus has strong critical hit abilities, her best Psychubes should have a Critical tag. There aren't many high-quality Critical Psychubes available as of's global launch, but there are a few options. As the game updates, keep an eye out for new Critical Psychubes that can work for more of Regulus's attacks.

Thunderous Applause is the best Critical Psychube available for Regulus in. This wonderful 6-Star Psychube provides up to a 16% Crit Rate bonus. This can stack with both Regulus's naturally high Crit Rate and her 50% Crit Rate bonus from Restless Heart. You can only trigger Thunderous Applause's Amplification with Regulus's single-target Incantation, Treat For The Ears, but it is worth it. If you score a critical hit with this Incantation, Regulus gets up to a 32% Crit DMG bonus.

If you don't have Thunderous Applause, An Afternoon Nap is the go-to replacement Psychube. It is essentially a 5-Star version of Thunderous Applause with
