SCP Foundation

I can't do a line by line right now, but after a cursory look I can give you a few tips:

Bold your section headings. This makes the separation of ideas easier, and provides visual breaks to the huge wall of text.

I would consider removing a lot of your Strikethrough text, because it pretty severely clutters up the page and makes in unnecessary difficult to read

I also suggest cutting down your test logs, as they all pretty much amount to the same thing, but take up a huge portion of page real estate.

This idea is pretty much just a generic magical item. It brings stuff to life, and that's about it. It needs more backstory or less bland effects to really be a unique and successful skip.

The first thing to take care of with this is the multiple spelling and formatting errors, especially with the random crossing out, which seems to be because you used two hyphens for SCP-1 and SCP-2. I'd also recommend you put the test logs in a collapsible box.
