Hypothesis #18 had failed like all that came before it. It seemed no amount of spell editing would force open this last lock and yet, the desire to see it open has already caused Ozymandias to reinvent the wheel eighteen different times. He knew there would be unfathomable depths to the magecraft he had specialized in, but never had he been confronted with something so esoteric that it forced him to put it into practice. This door had proven to almost be a crash course in how his spells could be utilized and that made it too valuable to give up on even if this all seemed fruitless.
Oz picked back up the one weapon he had in case of emergencies, an enchanted dagger that he had forced a barrier onto and then rewrote so that instead of protecting the knife from damage, it instead allowed him to create barrier circles by carving the boundaries into the ground. He had been using it for a different purpose currently though, he needed more room to take note than a piece of paper in his journal offered and so he took to carving his formulas into the ground around him. The mad scribbles often overlaying one another. His mind raced as he started to write down more ideas equations with only one last idea in his head. If the circuit is broken, he'd have to fix it. He couldn't expect a vault with missing cogs to open even if he knew the code.
Suddenly, a tingle went up his spine as he sensed someone enter the range of his detection spell. No, that's not right, they were already within range and dangerously close. He started turning to face his visitor before she even spoke, eyes wild like a beast caught in a cage. Of course he was struggling, and last thing he needed was more distractions. It risked him missing fallacies within his arguments and hurting himself from forcing a spell he didn't have enough expertise to cast. On a different note, if she was capable of slipping past his detection, then the gun in her hand was no empty threat.
"I'm already going as fast as I can, this isn't exactly high school algebra I'm doing here. And waving that weapon in my face isn't helping me think y'know? I'm probably 23 different establishments deep into trying to rewire this door back together so that it can actually be lock-picked in the first place. Not even I'm keeping up with all the intersections of all the rules I've put in place. For all I know, if I stand up my body may unravel as the electromagnetism holding my atoms together fails. So, unless you want to join me in this spiderweb, how about you put the weapon away and we be civil about this?"
Besides his new "friend", the howling laughter is the only sound he's heard for hours. The first girl was a big enough problem, so two was not something he wanted to deal with. Oz stared at the scratchings on the floor, picking apart ideas and tossing them aside without testing them. One more failed attempt and this lunatic may just shoot him. He needed to be certain, he needed an answer. He could almost feel his father's hand on his shoulder like the man used to do whenever Oz was struggling with a test, but this test was different. His father's designs were more intricate and purposeful, each step you made gave you an answer on how to take the next. This teacher was more strict, just a red 'X' on any proposed solution that was incorrect. It almost felt like this door was made on accident.
As he thought, Oz scribbled away while making sure to never complete the barrier loop around him made from his etchings. He needed to get close to that result in case things took a turn for the worse, but for now it would only incite the violence he wanted to avoid.
The fourth seal always causes the others to lock back up, any tampering with it leads to a reset within the spell. Well, not exactly any tampering, but any that seems likely to break it. Order doesn't matter, doing all 4 at the same time doesn't work, there's no counter spell on the door or if there is then not one I can invert, it's not on a timer, so what is causing it to lock back up? If this was a real lock then I could put tension on it in order to keep any set pins from falling back in place, but I don't have that luxury here and keep having to do my work over and over again. I almost wish it was as simple as there being someone on the other side that just keeps recasting the spell every time I get it open but I'm not noticing that kind of frequency. Removing complexities leads to a reset, adding them feels like I'm patching holes but I keep reopening them when I try to turn this last lock.
A crossroad had been reached. He was going to have to try some poorly thought out ideas to experiment with how the door reacted if he had any hope of getting it open. If Oz was only going to get one chance, then he was going to try all of them at once. Multiple ethereal formula crackled like electricity around Oz, as he wrote up an equation to overcome the first seal, an equation to establish that the seal could not lock while the fourth seal was locked, an equation to write up a new barrier seal to replace the position of the first that was still locked but easily opened, and then he maintained tension on the first seal by constantly putting energy into the unlocking spell. He repeated this process with the second and third seal, with his hope being that they could not lock unless the fourth was unlocked but if all were unlocked then the door would have some non-zero amount of time that all locks were open. Then the tensions spells would keep re-unlocking the seals, and hopefully it wouldn't take so much energy that it was impossible to open the door while the cycle was going. In addition, there was also the hope that the first three wouldn't even lock up again, because new locks had been put in their place and that could lead the fourth seal to be tricked into believing that they were already locked. The final step was writing up a barrier that constantly wanted to open but couldn't like a pen spring. Once pressure is applied to attempt to lock the barrier fully, it will crack open and unlock. Oz then bound that seal to the fourth seal, in the hopes that a barrier that keeps closing when opened could be balanced out be a barrier that keeps opening when closed. Brute forcing everything open at once wasn't exactly elegant, but no one could belittle a man writing twelve magical formula at the same time.
