That fixed the pastebin issue but now the second part where it’s supposed to say super effective, not very, etc. is saying invalid token? Any idea what the hang up is there?
Your first issue is that you’re not using the raw version of the Pastebin, your second issue is that you’re not using the proper quotation marks: “”, instead of "", also, you can clean your command a bit this way:
$(eval p=$(urlfetch json https://pastebin.com/raw/6Qef9Ld7); r=["It misses...","It's super effective! $(touser) faints!","It's not very effective..."]; `A wild $(user) appears and attacks $(touser)! $(user) uses ${p[Math.floor(Math.random()*p.length)]}. ${r[Math.floor(Math.random()*r.length)]}`)
