How to unlock the Diamond Ring achievement in Ben 10 - Definitive Guide
OnceFallen
Diamondhead's ability is where he shoots out diamond lasers (at least they look like that) in a spread pattern in front on him. For this trophy you must just hit 10 enemies with one use of the ability. The easiest way to get this is to go to the stage The City and during the second fight there will be way more than 10 enemies you will do battle with during it. Use Grety Matter's vortex ability and try to get more than 10 enemies sucked into to so they are grouped together, then quickly switch to Diamondhead and use his ability to hit the group. As soon as you hit 10 enemies with a single Diamondhead ability attack, the trophy will pop.
