First of all, you have to get a cloud bottle, a sandstorm bottle and a blizzard bottle, all equipped with equipment that can jump at two levels.

Then you need three flash balloons, and this one has a jumping height. You look everywhere for boxes for these ornaments, and look for them whenever you have the chance. After finding them, you need to buy something that looks like a bookshelf from the goblin merchant. I don't remember the exact name.

Then you can synthesize ornaments (in fact, these three things are quite useful in the early stage, but the rocket boots are much better than the goblin businessman)
