When I was looking for Unlimited Blade Works’ chant, I redirected to somewhere not quite where I wanted. And then I remembered seeing the chant in Shirou’s page. …except that now I get redirected to somewhere useless.
This certainly feels like the case when I looking for pages about certain game. I decided to open the wiki’s history and indeed the chant is there.
Conclusion: if you feel the information provided by Wikipedia is not as complete as you expect (especially on popular things), try checking its history to see if there’s ‘better’ version of the article…
(like this one or this – both are completely sfw links)
