In truth, this was the scariest part of your entire plan, entirely because of one of the biggest, most major weaknesses of being a cypher: your drain powers had no off switch. Once you touched magic, it was getting sucked dry whether you liked it or not, and trying to stop was like trying to stop taking a piss once you’d started. And unlike pissing, you had zero control over how fast or slow you drained magic: your body would continue draining at full tilt until either the source was empty, or you hit your upper limit on magic capacity.
