Ok, I'm in Madra at the moment, and I've just got the Cyclone Chip. I've tried to complete Madra Catacombs, and I can't because I don't have the Tremour Bit.
I'm trying to get it, and apparently there is a ladder outside the city walls that allow you to get the Tremour Bit.
One small problem.
I don't have a ladder.
Is the Tremour Bit permanently missable? Are you meant to get it earlier, and not getting it then means you cannot get it now? If so, that sucks, as I didn't know the second ladder existed.
If not- how do I get the ladder to appear?
