Primeval Currents (じゃぶじゃぶ旧海道 Jabujabu Kyū Kaidō, Stirring Old Sea Circuit) is the 4th sub-chapter of Uncanny Legends, and the 53rd sub-chapter overall. It was added in version 7.1, and is currently available up to 2★ difficulty.
Difficulty in this Uncanny Legends sub-chapter is rising as the stages progress. The first two stages are arguably the easiest in the sub-chapter. Palcaccio Waters and Rutsborg Vortex are by far the hardest stages in this subchapter, although Utsubobo Seamount and Frontier Dawn shouldn't be too bad.
- 2★ difficulty for this sub-chapter multiplies enemy strength magnifications by 150%.
This sub-chapter introduces one new enemy:
- Othom: Mooth's Relic/Floating variant, with high health, damage and speed, plus a 100% chance to Curse cats for 2 seconds. Notably, he attacks from a range of 340 but hits cats up to 440px away, allowing him to outrange many more cats.
