Arkaim’s question here got me thinking if there is a better way to track things like Mirror Gazing and Ghoultouched and the like. (Long ago I considered adding an “info box” type thing which lists some additional information in small text in the corner but never figured out the formatting for it.) Looking at the way that the item pages are set up with the templates for stash, salvage and crafting — these have been in use for a long time and seem (relatively) straightforward to use. It seems something similar could be used for opponent pages.
As an example, I edited the Dazzling Cloud. Thoughts? (Formatting needs a bit of tweaking.) I think this would help make it clear when opponents haven't been explicitly tested.
Anything else to add to that would be useful to know? Most of the rest of the things listed on the Opponents testing page are pretty flag-specific (eg. are you human for Unexpected Grab). Things like testing tome of binding or salving kit are generally already listed separately, and occasionally have additional requirements, although would be good to know if someone has explicitly tested those sometimes.
Charmed Chain might be good to add though I don't know if it's worth adding to all the pages because a) it's specific to that unearthly item and b) Kinak confirmed there's not a "has fangs" flag, so it must be based on some other external factors. (Though, when prompted, the centipedes were added in the spider-type category, so there also seems there is something non-obvious that can be done on the backend to flag these.)
