Hi there. I discovered Card Hunter last night, and I'm really liking it so far. I have a question though. I assumed that the level shown on equipment (level 2, level 5 etc) are the levels you need to use that equipment. However, it seems I can use level 2 equipment on level 1 characters. Can someone explain this please?
It's just a measure of equipment power, and of the level of adventure where you can get that equipment. It also affects the prices of the equipment in shops. Buying equipment that's above your level costs more gold. Thirdly, as you get up to 7 or 8, it is (somewhat) related to power token usage.
Higher level items may have power token requirements, which require you to be high enough level to have enough power tokens to equip them. You start getting minor power tokens(blue bead icon) at level 7, and major power tokens(gold bead icon) at level 15. Item level itself doesn't really matter, and only seems to be a very general indicator of how good an item is. If you've gotten far enough in the game to get the free multiplayer party(level 6 or so), it might make more sense as the party members come with a bunch of high level items, so you can see how they used some high and some low level items in a build for level 18 party members.
