It Was My Mistake adds a terrifying entity called Stop that stalks the player and becomes more dangerous over time. Looking back at it will cause it to chase and attack, leading to a jumpscare encounter.
Track Stop's impatience level with the Entity Level Preview, displayed at the top center of the player's inventory. If needed, the Potion of Rejuvenate can be used to reduce its level.
Don't look at it...
Stop now features a new model, simple animations, dialogue, and can attack nearby mobs. After killing a mob, it also has a chance to leave behind something unexpected.
Defeating Stop rewards materials used to craft Talisman → Ring → Artifact → Relic. Each tier further reduces the chance of Stop spawning after killing mobs.
The final Relic can be crafted into a powerful sword. Defeating Stop with this sword permanently prevents it from spawning, while another craftable item can restore its spawning.
This mod focuses on slow-building horror, progression, and tension rather than constant jumpscares.
JEI is recommended.
