Slime Cat Achievement question

Can I do some fated raids on one character then the rest on another? Or does every fated raid have to be completed on the SAME toon for me to get the mount?

You can use multiple toons since the meta achieve is account level (blue) as opposed to regular character specific (yellow). Hover your mouse over the title of the meta achieve and you will see it says “Progress on any of your characters will count towards this achievement”.

Ohh ok I see - thanks so much!!
