Just trying to get element without fighting bosses because we have difficulty so high plz help

Wyvern trench, Space biome bushes and snow mountain have crystals that give shards.
Extinction has Structures that give dust that you can convert into element.
Purple OSD's can give element, Red OSD's can give element Shards.
You can also tame gachas in the Extinction biome and make some that way
