How do rogues switch weapons?

We have started a game of Heroes & Treasure, a family-friendly tabletop RPG accessible to kids. Looking ahead, I notice that at level 5 rogues gain the ability to switch between weapons:

Level 5: Can switch between any available weapons at will.

This ability is confusing to me, because throughout the rulebook (about 8 pages) there is no mention of equipment or different kinds of weapons. I can’t speak to all of the published levels or adventures, but the 2 levels we are playing tonight also don’t mention any specific equipment. There are also no tokens for different equipment.

So how does the rogue’s ability to switch weapons work? Where do the weapons come from?
