Build an effect here, download the YAML, drop it in. Nothing is sent anywhere — this runs entirely in your browser.
Both become comments at the top of the file. They change nothing about how it runs — they are there so whoever opens this in six months knows what it was for.
Add as many triggers as you like — any one of them fires the effect. Add none for a permanent effect, which simply holds while its conditions are true.
Only filters your chosen triggers actually support are shown, so you cannot write one that never matches.
Add as many as you need — all of them must pass. They are re-checked continuously, so a permanent effect switches itself off when one stops being true.
