... but... how did they build a tight rope that long????
The rope alone would weigh over 300 kilograms... way way more. To have it tight without sagging over such a massive distance would require so much tension nearly all materials beyond braided steel cable would snap.
building the mounting point to hold the ropes in place alone would be a mammoth task and buying the rope would cost as much as a house in the middle of a walled city in the time frame depicted.
ignoring all the logistical problems and the laws of physics - how did they set up the ropes??? the initial rope must be strung over hundreds of buildings and the wall and brought up onto the mansion. He had his team of witches do it? How did he communicate? How did they not get seen doing what is hours and hours of work?
This is a STUPID escape. Needlessly flashy with 0 thought put into it. I was hoping for a fun series that plays with magic tricks in a way that I can "suspend my disbelief" because nobody is actually going to save the day with slight of hand and wire work... but this... this is complete nonsense - he may have well used the force, summoned a demon and teleported for all the logic this escape had.
