Technically, Genshin Impact has an inventory limit. In practice, well, suffice to say that the inventory limit is 30,000. Naturally, this means that players should loot its environments to their heart’s content, which will be very useful because just about everything can be put to good use one way or another.
As for the various sources of items, there are a number of them to keep in mind. First, there is the option of defeating enemies for a wide range of items, which is something of a classic when it comes to RPGs. Players will want to grab every single one of these at every single opportunity. Even if they don’t have a use for a particular item, there is always the option of either trading it in or turning it into something else. Second, there are a lot of items that can be harvested from the open world environments. For example, interested individuals can hit ores for their content, though they will want to bring a two-handed weapon to make the process faster. Likewise, area-of-effect spells can be used to turn boars and chickens into edibles. On top of this, there are some flowers that need certain elemental skills before they can be harvested, which tend to be rather valuable.
