Age Of Magic - Spellbook - Hero Page

I made a companion app to an IOS game I've been playing called Age of Magic. It's a fantastic game but there's a mechanic they don't really make clear, so I built a mobile-friendly app that lets you see what hero's skills can set "marks" and when you pick the skill you can see all the other hero's skills who can use the "mark". Here a hero is selected, describes the skill and mark, and lists other hero's skills that trigger the "mark".

I coded Spellbook using community game assets and Vue.js, Firebase, and AWS S3 :
