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.

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.

Using Reverse 1999 Psychubes that boost damage is recommended for the best Sweetheart build. Listed below are the best Psychubes for this DPS character:

Blasphemer of Night: This 6-star Psychube grants an 18% increase in her Incantation skills at level 60. If the enemy has two or more Neg Status, Sweetheart's damage-dealing ability increases by 24% at Amplification level 5.

Luxurious Leisure: Her Ultimate strength increases by 18% at level 60 when equipped with Luxurious Leisure. At Amplification level 5, her damage-dealing ability increases by 9% after she casts her Ultimate.

Brave New World: The 6-star Psychube, Brave New World, also increases Sweetheart's Ultimate strength by 18% at level 60, like Luxurious Leisure. At Amplification level 5, her basic skill strengthens by 40% after she casts Ultimate.

Yearning Desire: The 5-star Psychube, Yearning Desire, boosts the character's Incantation power by 15% at level 60. If the enemy is in Stats Down or Neg Status, her damage-dealing ability increases by 16% at Amplification level 5.

Timekeepers can use any Psychubes from the list above for the best Sweetheart build. However, Yearning Desire and Blasphemer of the Night significantly help her deal more damage.
