I figured we should have a place to post what we have so tragically learned the hard way.
- Don't climb down ledges with stuff in your hands. It may hit you on the head and you'll feel like a doofus.
- Same goes for throwing any objects near walls. They may bounce.
- Down+Y drops a rope downwards. This is good for setting off arrow totems when you're out of other things to throw.
- If you're going to trigger the boulder, double check on any shopkeepers in the area. You will pay for your crimes otherwise.
