Just had knights return from first attempt at finding burning ember-nope-so it's not gonna be a guarantee on your first trip,no diamond from mines,and my one adult valentine lamb didnt give up anything either.The search for the special 3 things seem to be like the "golden" drops,rare,so this is where most of us are gonna have to be patient(ugh).so start stocking up on sweet feasts(a bakery woulda been very handy with this interesting update)
