Review & Analysis

iDoll Sun is an R-rarity Iron Supporter built around self-buffing rather than team support. Burst skill Sunset massively boosts her own Max Ammunition Capacity, letting her fire continuously without reloading for an extended window. Skill 2, Sunlight, has a random chance to trigger an ATK buff on herself when attacked, while Skill 1, Sunshine, raises her own DEF after landing 10 normal attacks. As an R-rarity, tier F unit, iDoll Sun is mostly relevant in early rosters and offers little team-wide support.

General guideline: level evenly to 1/1/1 for temporary use; if pushing further, prioritize Burst (797.5% max ammo boost) since it nearly removes the need to reload during sustained fire.

Strengths & Weaknesses

Strengths

Her Burst boosts her own max ammo capacity by 797.5%, nearly eliminating the need to reload for 10 seconds.
Skill 1 self-buffs DEF after 10 normal attacks, helping her hold up better during sustained fire.

Weaknesses

Very low R-rarity base stats, unable to hold up in harder content.
Both buffs only affect herself, offering no support to allies — very limited squad value.
Skill 2 only has a 20% chance to trigger when attacked, making the ATK effect unreliable.
