Reverse 1999 Sweetheart build: Skills analysis, best Psychubes, Insight Materials and teammates

Sweetheart is a 5-star Plant-type Arcanist in Reverse 1999 who inflicts Reality damage with her incantation skills. She has DPS and Control tags and can inflict the Daze status effect, which restricts enemies from using their attacks. This DPS Arcanist can also cast the Enchanted status effect, which reduces the damage she takes by 10%.

Sweetheart's incantation skills can’t inflict much damage at base form like other damage dealers. Therefore, Timekeepers must equip her with the best Psychubes, use teammates that increase her damage potential, and carefully plan her attacks to make the most out of her kit.

This article explores the best Sweetheart build in Reverse 1999 and recommends the best Psychubes and teammates for her.

Reverse 1999 Sweetheart build: An in-depth skill analysis

Sweetheart attacks one enemy with her Ultimate and basic incantation skill, Dud, and deals damage to all enemies with the Slight Breeze incantation skill. Here is a detailed explanation of her abilities and how to use her kit:

Dud (basic): The incantation skill, Dud, attacks a single target, delivering 200%/300%/500% damage with one/two/three-star rank cards.

Slight Breeze (basic): Her other incantation skill, Slight Breeze, is a mass attack that delivers 135%/200%/335% damage with one/two/three-star rank cards. Slight Breeze also inflicts 30%/45%/75% additional damage with one/two/three-star rank cards if enemies are in Stats Down, Neg Status, or Control status.

A Good Dream Tonight (Ultimate): The Ultimate, A Good Dream Tonight, inflicts 400% damage to a single target and reduces Reality and Mental defense by 20% for 3 rounds. It also applies the Daze status effect for one round. The Daze status effect stops enemies from using any skill.

This Beast Afflatus Arcanist can inflict Daze and reduce the enemy’s Mental and Reality defense. While Daze is pretty helpful, the debuffs are not particularly useful since Timekeepers must build her Ultimate to cast them.

Sweetheart's Ultimate becomes robust at Portray level 5, which increases its damage to 600%. Timekeepers are advised to upgrade her Portray levels to dish out impressive damage.

Her Slight Breeze incantation skill can only deliver significant damage if enemies are in Neg Status, Stats Down, or Control status. Since she can debuff only with her Ultimate, Timekeepers are advised to bring a separate debuffer like Bkornblume to boost her damage.

After unlocking her Inheritance, A Low Whisper, she casts Enchanted status on an enemy who attacks her. When this status is triggered, she takes 10% less damage from the attacker. Although it can stack, each stack is timed independently, which does not prolong her survivability. She needs a healer to stay longer in the battle.

Timekeepers are advised to max out her upgrades and take advantage of the damage bonus Sweetheart gains from the Slight Breeze while using her in the battle.
