>>66333514The "|" character is prompt alternating syntax. It alternates between anything joined with "|" and I use it to invoke related tags without adding undue weight. You can also use it to join unrelated tags for interesting results. For example, this is a "horse|motorcycle|cow". What it means is that on step 1 it inserts "horse", step 2 it inserts "motorcycle", step 3 it inserts "cow", then repeats.
