only singles, doubles and triples. if i'm right, 105, 45 doubles and 10 singles will be here. 160 in total. less of a stretch than the last 10-element collab, but still a lot. there can be new singles, or already existing ones. (only fanmade ones, precreated is fine.) the hybrids will be made from the creators of its elements. (together)
"complex" elements are monsters that are based off of things that arn't too well known
