ReGrettaBle Relay

Taking a break? I don't need a break yet!

This is a public version of a practice variant of ReGret-B Filtering, designed for users who are not comfortable calculating 3 operators within 90 seconds. This module consists of 3 stages where you must perform different operators on each stage to disarm the module. Each operator is calculated uniquely like ReGret-B Filtering however you will have to do at least 1 of these rather than being able to wait it out.
When you are ready, subscribe to ReGret-B Filtering for the true challenge.

Original variant by Obvious
Practice variant by VFlyer, modified for ease of difficulty
