Maybe a kind of chests that stay still when you are far, but when you are near it grows legs for the chests and begins running away from you , . Another one could be the same as before, but instead of running away from you they attack you. Also shadow chests would be another nice type, ones that only are visible if you aim them with a flashlight, or a source light different than solar light.
Reminds me of those mimic chests from Terraria, and probably a bunch of other games. I don't really like the shadow chests idea, I feel like I'd always be missing something if I wasn't constantly flicking my flashlight around while exploring.
atleast for more variety of chests, about shadow chests, was only for adding another kind more, so if you have to exploring with flashlight around and they are hard to find, maybe they would have nice rewards(a little better than habitual, maybe a vanity armor or some blueprints about shadow ) and this in addition with other imaginable kind of chests, i want to see variety. And about chests with legs i thought it would be a funny idea, so the chest is a little hard to take, maybe could have better chance of better rewards, i never played terraria .
Also there would be locked chests or something similiar, so you have to find the key or better, you could craft it, there would be different kind of locks,for example you could craft iron key, silver key, or gold key, for different ranks of locks, the more expensive it is to craft the key, you can get better rewards from that chest, if its locked with and iron lock you should use iron key, so the rewards inside are not so amazing than others with gold locks. Also chests with traps for the time you open them? maybe dealing a little damage or an explosion that pushes you far,
