Naegleria Fowleri

Named after the real brain-eating amoeba Naegleria fowleri, this head parasite reshapes the wearer across the entire arc of a fight. StatusOnBattleStart fires an effect at the beginning of combat, while StatusOnBattleEnd fires another at the conclusion, bracketing every battle with parasite-driven changes. CatPartsSizeScale physically alters the wearer's size, potentially affecting hitboxes or movement. At low health, PassiveAtStatThreshold activates a final effect — mirroring the real pathogen's most dangerous phase. A complex, reward-dense item for players who understand all four triggers.

The four-passive interaction creates a layered timeline: the battle-start status applies immediately on engagement, then the parasite acts throughout the fight through size scaling and any threshold effects, and the battle-end status closes each fight with another change. The size scaling from CatPartsSizeScale may affect movement speed, reach, or hitbox calculations in ways that are not immediately obvious from the item description alone.

Naegleria Fowleri is a knowledge-dependent item: equipping it blindly can produce confusing results, while a player who knows what each trigger does can leverage all four effects as a coordinated kit. Before committing the head slot to it, identify what status each trigger applies in the current run context. If all four effects are advantageous, this becomes one of the most impact-per-item pieces in the game.
