For specific topics/heroes, etc, there is the search feature. These should be master topics. The ones you give everyone, every time; the daily or semi-daily links.
Been working hard on the Fandom Wiki, to make that thing top notch. So much of it actually combines 2 or more of the resources stated above, while still linking to them.
For instance, combining information about the Training Camp from both the E&P RPG Wiki and Coppersky’s Compendium so that there’s a full listing of upgrade and research costs (neither had complete lists), while also pulling in the TC20 Results thread as a source to declare precise percentage droprates. We’re up to over 300 pages now, so it’s pretty darn comprehensive.
Also, would love more collaborators. Please consider becoming one. That wiki is easy to find through Google and having a quality wiki improves the gameplay experience of everyone (not just those of us who visit the forums).
I only have one incomplete sheet/project on the list right now (because S2 is still being revealed). Let me eyeball yours.
EDIT: Added the Wikia - Categories List
EDIT2: I like your tool! If folks aren’t careful, they might misunderstand that while they can level a 5* to tier 3, they can’t final it…but using one’s eyes helps! Lol
Might I request that for the Wikia, either the main page, or the Hero Information page be the link? If you preferred the Categories page due to all of the Hero lists, there’s a condensed version of the hero-only categories on the Hero Information page.
