You do need to pass a fight or a lore check before you can spend clue tokens to seal a gate, right? I mean, I know you need do, and the rulebook says so too, but the arkham wiki says this:
In order to Seal a gate, you go through the Gate and return as normal. But instead of making the Fight or Lore check upon your return, you just spend 5 Clue Tokens and you immediately Seal the gate and place an Elder Sign on that location. No roll necessary.

Have they changed that or is it just a mistake in the wiki?
