Immaculate Heart

Immaculate Heart is a very rare trinket that boosts both physical damage and spell damage while also applying a self-status effect with every basic attack. The combination of offensive stat scaling and self-buffing on every swing makes this one of the strongest offensive trinkets in the game. It rewards aggressive playstyles by stacking power faster the more your cat attacks, and the dual damage type scaling makes it versatile across physical and magical builds alike.

Physical damage and spell damage bonuses apply to different damage sources: physical boosts weapon attacks and STR-scaling abilities, while spell damage boosts INT-scaling or magic-type abilities. Running both simultaneously means every offensive ability in the cat's kit benefits from one of the two boosts, effectively providing a universal damage increase. The self-status on basic attack adds cumulative power each turn, likely stacking an offensive buff that grows as combat continues. Cats that attack every turn quickly accumulate multiple stacks, creating a snowball effect.

Immaculate Heart is an elite offensive trinket for high-attack-frequency cats. Melee fighters with multi-hit attack patterns generate self-stacks rapidly and see the largest relative damage increase from the escalating buff. The dual damage scaling means even hybrid builds that split between physical and magical damage output get full value. Pair with abilities that scale off whichever damage type receives a larger relative boost for the specific cat. This trinket is strong enough to justify the very rare slot on almost any combat-focused build.
