Spade Officer
Spade Officer closes out Act 4 of Rose Kingdom's Story campaign, the final officer-titled boss before String Demon takes over as the zone's true Act 5 finale. The full officer set runs Heart Officer at Act 1, Club Officer at Act 2, Diamond Officer at Act 3, and Spade Officer here at Act 4.
Its wave carries the same Regen1 and Reinforced base seen throughout Rose Kingdom's officer fights, plus a Transformer modifier that is unique to this specific encounter among the four: once Spade Officer's health drops below a set threshold, it transforms into a tougher form rather than simply continuing the fight at reduced health. That makes Spade Officer the only one of the four officers with a hard phase change to plan around, on top of the same damage-reduction and regeneration check the earlier acts introduced.
Like every Boss-type enemy, Spade Officer carries a hidden tag adding a flat 20% health multiplier and a 30% speed penalty on top of its listed stats, moving at the Boss tier's baseline speed multiplier of 1.68 and modeled at 0.8x scale. Incoming Stun and Rewind effects cap out at 10 stacks rather than being fully blocked, since Rose Kingdom's wave list does not carry the Immunity modifier.

Reinforced's flat 30% damage reduction and Regen1's steady healing reward sustained damage over a single burst attempt, the same core check the other Rose Kingdom officers use.
Spade Officer is the only one of the four officers with a hard phase change to plan around. Saving cooldowns or burst damage for after the Transformer threshold triggers helps avoid getting caught off guard by the tougher post-transform form.
