Tactical Escape: the character instantly exits the battle, losing all levels. The higher the level, the faster the enemies finish pursuing him and drop their aggro, and the higher the chance of a successful escape. At high levels, the character can enter stealth mode directly in battle (like in Skyrim with high stealth).
There is no parameter that controls aggro. Whether the pursuit will continue or not depends on the specific enemy and the specific situation. But a skill that allows entering stealth mode directly in battle can be created. From level 4 to 6, with a certain duration.

Henry, unaware that Lin had already given her pocket to the healer, writes her a letter describing the events of the day and that she is invited to the hot springs if she has time, because why not. He adds that they will all be taken back on horseback, so they should be back at the tavern by night.
