yes the black Dragon boss drops holy grails instead of potions now but don't expect too much from it, I have an account that recently finished the black Dragon boss one hit killing with 2% permanent luck and luck cloak for last 25 levels and only got 4500 holy grails...perhaps admins could raise the drop rate on the grails to be of more use to most players since even 4500 grails doesn't add much (it would have been about 13500 credits if they had been potions which could have easily allowed me to get a banner level 3 and add 7500 strength and 5000 direct damage, which would have been far better than simply 4500 strength)
